Convert land or plot area from acres to square meters, or switch direction to convert square meters to acres. Choose your decimal places and copy the result.
Start with an existing area measurement, choose your units, and review the converted result.
Select acres to square meters, or use the reverse option. Check the input label before entering your measurement.
Enter zero or a positive number. For fractional acres, use decimals: 0.25 for a quarter acre or 0.5 for half an acre.
Choose two, four or six decimal places. Use more places when you want to reduce rounding, especially when converting a small area to acres.
Check the result and calculation, then select Copy Result. If automatic copying is unavailable, select and copy the text shown below the button.
Check your starting unit: This tool converts area, not individual side lengths. If your measurement is in square feet, use the square feet to square meters converter directly. Switching direction keeps your number and changes its unit.
Multiply acres by 4,046.8564224 to get square meters. For the reverse conversion, divide square meters by the same factor.
A plot listed as 0.25 acres can be expressed in square meters by multiplying its acreage by the conversion factor.
Square meters = acres × 4,046.8564224
0.25 × 4,046.8564224 = 1,011.7141056 m²
A rectangular plot measuring 20 meters by 50 meters has an area of 1,000 m². Divide that area by the conversion factor to express it in acres.
Acres = square meters ÷ 4,046.8564224
1,000 ÷ 4,046.8564224 ≈ 0.2471053815 acres
One acre describes area, not a fixed shape. It equals 4,046.8564224 m², whether the plot is rectangular, square or irregular. See Math Is Fun’s definition of an acre for the unit relationship.

Find answers about acreage, square meters, fractional plot sizes and conversion rounding.
One international acre equals exactly 4,046.8564224 square meters. Rounded to two decimal places, that is 4,046.86 m². Multiply your acreage by the full conversion factor before rounding the final result.
A quarter acre is 0.25 acres. Multiplying 0.25 by 4,046.8564224 gives 1,011.7141056 m², or 1,011.71 m² rounded to two decimal places.
It is slightly smaller. Half an acre equals 2,023.4282112 m². An area of 2,000 m² is approximately 0.4942 acres, which is about 23.43 m² less than half an acre.
Enter the fraction as a decimal: 0.25 for one-quarter, 0.5 for one-half, or 0.75 for three-quarters. For a mixed value such as 1½ acres, enter 1.5. The input accepts decimal numbers rather than slash fractions.
Acreage alone does not determine the side lengths. Different shapes can have the same area. If a one-acre plot is square, each side is approximately 63.61 meters. A rectangular or irregular one-acre plot can have different dimensions.
Yes, if you already know its total area in acres. The conversion factor is the same for every plot shape. If you only have dimensions, calculate the area first, dividing the plot into measurable shapes without counting overlapping areas twice. For dimensions in feet, the square footage calculator can help calculate the component areas.
No. An acre equals 4,046.8564224 m², while a hectare equals 10,000 m². One hectare is approximately 2.4711 acres. Check your starting unit before entering a land measurement.
Rounding removes some digits from the displayed result. If you enter that rounded number for the reverse conversion, a small difference can appear. Use more decimal places to reduce this difference. Switch Direction keeps your original input number; it does not automatically replace it with the converted result.
Enter your acreage, review the calculation and copy your result. You can also switch direction to convert square meters to acres.
