Area Conversion Chart and Calculator for Sq Ft, Gaj, Acre

Why You Need a Chart and a Calculator

Sometimes you do not want to learn a method. You just want a number you can trust, fast. A conversion chart gives you the answer for common sizes at a glance. A calculator handles every other size. Used together, they cover almost every area question in India.

This page gives you ready charts for sq ft, gaj, sq m, acre and hectare, and then shows how to use our area converter for sizes that are not in the chart. Every example uses rupees, lakh and crore.

Background: How the Chart Values Are Built

All values below use these standard factors: 1 gaj = 9 sq ft, 1 sq ft = 0.092903 sq m, 1 acre = 43,560 sq ft = 4,046.86 sq m, and 1 hectare = 10,000 sq m = 2.47105 acres. Numbers are rounded to two decimals unless shown otherwise.

A chart is only as good as its factors. So if you build your own table in a spreadsheet, keep these exact values and round only at the end.

Chart 1: Square Feet to Gaj and Square Metres

Sq ft	Gaj (sq yd)	Sq m
500	55.56	46.45
600	66.67	55.74
800	88.89	74.32
1,000	111.11	92.90
1,200	133.33	111.48
1,500	166.67	139.35
2,000	222.22	185.81
2,400	266.67	222.97
3,000	333.33	278.71
4,000	444.44	371.61

Most city plots fall in this range. A 30 ft by 40 ft plot is 1,200 sq ft, and a 40 ft by 60 ft plot is 2,400 sq ft. Both are very common sizes in Indian layouts.

Chart 2: Acres to Sq Ft, Gaj and Sq Metres

Acres	Sq ft	Gaj	Sq m
0.25	10,890	1,210	1,011.71
0.5	21,780	2,420	2,023.43
1	43,560	4,840	4,046.86
2	87,120	9,680	8,093.72
5	2,17,800	24,200	20,234.30
10	4,35,600	48,400	40,468.60

Notice the pattern. One acre is 4,840 gaj, so you can find any acre value by simply multiplying by 4,840. This is a useful shortcut in cities where plots are sold per gaj.

Chart 3: Hectares to Acres and Sq Ft

Hectares	Acres	Sq ft
0.5	1.24	53,820
1	2.47	1,07,639
2	4.94	2,15,278
5	12.36	5,38,196
10	24.71	10,76,391

Key takeaway: Remember three anchors: 1 gaj = 9 sq ft, 1 acre = 4,840 gaj, and 1 hectare = about 2.47 acres. With these, you can build most of the chart in your head.

How to Use the Calculator for Other Sizes

1. Open the area converter on DigiToolkit.
2. Type your size, such as 1,850.
3. Pick the from unit and the to unit.
4. Read the answer and note it with the unit.
5. Multiply by the rate if you want the total price.

If you have the sides of a plot in feet, find the area first with the feet to square feet converter, then convert the total.

Worked Example 1: A 1,500 Sq Ft Plot

Vikas finds a plot of 1,500 sq ft in Nagpur at Rs 4,200 per sq ft. He wants the gaj and sq m sizes for a loan form.

• From Chart 1: 1,500 sq ft = 166.67 gaj = 139.35 sq m.
• Total price: 1,500 x 4,200 = Rs 63,00,000, which is Rs 63 lakh.
• Rate per gaj: 4,200 x 9 = Rs 37,800.

If a broker offers a similar plot at Rs 40,000 per gaj, Vikas knows at once that the second plot costs more, since Rs 40,000 per gaj is Rs 4,444 per sq ft.

Worked Example 2: A 2.5 Acre Farm

Sarita is looking at 2.5 acres near Indore. The chart has 2 acres and 0.5 acre, so she adds the two rows.

• Sq ft: 87,120 + 21,780 = 1,08,900 sq ft.
• Gaj: 9,680 + 2,420 = 12,100 gaj.
• Sq m: 8,093.72 + 2,023.43 = 10,117.15 sq m.
• At Rs 3,000 per gaj: 12,100 x 3,000 = Rs 3,63,00,000, or Rs 3.63 crore.

As a check, the same land at Rs 1.45 crore per acre would cost 2.5 x 1.452 crore, which is also Rs 3.63 crore. The two routes agree.

Worked Example 3: A 3,000 Sq Ft Plot and Built-Up Limit

A family has a 3,000 sq ft plot in Pune. The local rule allows a floor space index (FSI) of 1.5. FSI values differ by city and zone, so they should confirm the rule with the local authority. Using 1.5 here only as a sample:

• Plot in sq m (Chart 1): 278.71 sq m.
• Allowed built-up area: 3,000 x 1.5 = 4,500 sq ft.
• Allowed built-up area in sq m: 4,500 x 0.092903 = 418.06 sq m.
• Plot cost at Rs 3,500 per sq ft: 3,000 x 3,500 = Rs 1,05,00,000, or Rs 1.05 crore.

They now have the sizes in both sq ft and sq m, which suits their architect, who works with metric drawings.

Benefits of Using Charts and Calculators

A chart gives instant answers for common sizes, with no typing at all. You can print it, save a screenshot, or keep it in a notes app. That helps when you are on a site visit with weak network.

A calculator fills the gaps. It handles odd sizes like 1,850 sq ft or 3.7 acres with the same precision as a standard row. Together, the two make a full toolkit for any area question.

Both also build trust. When your hand-made chart values match the tool, you know your numbers are sound. This is useful for students, brokers, builders and anyone who handles property talk each day.

Challenges and Limitations

A chart can only list a few rows. If your size is between two rows, you may be tempted to guess, and guesses create errors. Use the calculator for in-between values instead of estimating.

Charts also hide rounding. For example, the figure of 12.36 acres for 5 hectares is rounded from 12.3553. In a big land deal, that small gap can mean lakhs of rupees.

Finally, no chart can cover regional units that change with place, such as bigha or katha. For these, get the local value first, then add it to your own table.

Common Mistakes to Avoid

• Reading the wrong column. Gaj and sq m sit side by side in the chart. Check the header before you copy a number.
• Estimating between rows. Do not guess for 1,350 sq ft. Use the calculator for exact values.
• Using a chart with the wrong factors. Some charts online use 0.093 or 10.76. Check the source, and prefer exact factors.
• Mixing Indian and Western digit grouping. 2,17,800 and 217,800 are the same number. Read the commas carefully.
• Forgetting to convert the rate. If you move from sq ft to gaj, multiply the rate per sq ft by 9 as well.
• Applying a sample FSI or rate as fact. Local rules and market prices change, so confirm them before you decide.

Best Practices and Expert Recommendations

• Save the chart on your phone. Take a screenshot of the three tables so that they are ready on site visits.
• Use the calculator for the final number. Treat the chart as a quick guide and the tool as the final word.
• Add your own rows. If you often work with 1,800 sq ft or 2,800 sq ft plots, add them to your own list.
• Always note units. Write 166.67 gaj, not just 166.67. A number without a unit is easy to misread later.
• Check big deals twice. For deals above Rs 50 lakh, repeat the conversion in a second way, such as through acres and through sq ft.
• Confirm with the paper. The area in the registered document or approved plan is the legal one. Use charts to understand it, not to replace it.

For a quick sq ft and gaj match, the square feet to square yards converter does the job on one screen.

Try It Yourself

Pick a size that is not in the charts, such as 1,850 sq ft or 3.7 acres. Enter it in the free area converter and note the gaj, sq m and acre values. Then try the same size by adding two chart rows and see if the answers match.

Conclusion

Charts give speed and calculators give precision. Keep the three tables in this guide handy, remember the anchors of 9, 4,840 and 2.47, and use the converter for everything else. With both in your hands, any plot, flat or farm size in India can be read and compared in a minute.

How to Build Your Own Chart in a Spreadsheet

You can make a personal chart in a few minutes with any free spreadsheet app. It is a good exercise, because it shows how each number in the tables above is produced.

1. Column A: list your sizes in sq ft, for example 500 to 5,000 in steps of 100.
2. Column B: divide column A by 9 to get gaj.
3. Column C: multiply column A by 0.092903 to get sq m.
4. Column D: divide column A by 43,560 to get acres.
5. Column E: multiply column A by your local rate per sq ft to see the price in rupees.

Set the number format to two decimals and keep the factors in separate cells, so you can change them in one place if you ever need to. A sheet like this is also useful for brokers who show many plots to a client in one meeting, since each row answers the usual questions about size and price at once.

For example, a row for 1,800 sq ft will show 200 gaj, 167.23 sq m and 0.0413 acre. At Rs 3,800 per sq ft, the price column will show Rs 68,40,000, or Rs 68.4 lakh. You can check one such row against the calculator to confirm that your formulas are right.

FAQs

How many gaj are in one acre?
One acre has 4,840 gaj, since 43,560 sq ft divided by 9 gives 4,840. You can use this to convert any acre value quickly.

How many sq ft are in 1,000 sq m?
Multiply 1,000 by 10.7639 to get 10,763.9 sq ft. This is a quick check for larger plots and commercial spaces.

How many acres are in one hectare?
One hectare equals about 2.47105 acres. Two hectares is about 4.94 acres.

Can I trust a conversion chart for a legal land deal?
A chart is good for planning and comparison. For legal work, use the area stated in the registered document, the approved plan or the official land record.

What is the difference between a chart and a calculator?
A chart lists answers for fixed common sizes. A calculator works out the answer for any size you enter, so it is better for odd values.
