What is the Acres to m² Converter?

This tool converts acres to square meters, helping you express traditional land measurements in the metric system used by most of the world.

Why Convert to Square Meters?

While acres remain popular in the US and UK, square meters are the international standard. You might need this conversion when:

Filing international reports — agricultural data often requires metric
Working with metric equipment — irrigation, fertilizer calculators use m²
Selling to foreign buyers — international investors think in metric
Academic or scientific work — research uses SI units

The Conversion

1 acre = 4,046.86 square meters

This is a precise, internationally recognized conversion. A typical US quarter-acre lot (0.25 ac) equals about 1,012 m², while a 5-acre farm equals 20,234 m² (just over 2 hectares).

Acres vs Hectares vs Square Meters

In metric countries, large land areas are typically expressed in hectares (1 ha = 10,000 m²). One acre is approximately 0.4 hectares, or 40% of a hectare.

How to Use

Enter your acreage — type the number of acres
Read the result — square meters appear automatically
Copy as needed — use for reports or documentation

Common Acre Conversions

Quick reference for typical land sizes:

0.25 acres = 1,012 m² — standard suburban lot
1 acre = 4,047 m² — roughly a football field
5 acres = 20,234 m² — small hobby farm
40 acres = 161,874 m² — traditional "quarter section"
100 acres = 404,686 m² — medium-sized farm

Agricultural Applications

Many farming calculations (seed rates, fertilizer amounts, irrigation needs) are specified per square meter or hectare. Converting your acreage first makes these calculations straightforward.

Frequently Asked Questions

How do I convert acres to square meters?

Multiply acres by 4,046.86 to get square meters. For example, 5 acres × 4,046.86 = 20,234.3 m².

Why do agricultural reports need metric measurements?

International organizations (UN, FAO) and scientific journals use the metric system. Converting to square meters ensures compatibility with global agricultural databases and research.

How do I convert yield data from per-acre to per-square-meter?

First convert your acreage to m², then divide your total yield by the m² area. For per-hectare figures (more common internationally), multiply the per-m² result by 10,000.

What's a section and quarter section in metric?

A section (640 acres) equals 2,589,988 m² (about 259 hectares). A quarter section (160 acres) equals 647,497 m² (about 64.7 hectares).

Is square meters or hectares better for large farms?

Hectares are more practical for large areas. One hectare = 10,000 m² = 2.47 acres. Most agricultural statistics use hectares rather than raw square meters.

Can this help with carbon credit calculations?

Yes, many carbon credit programs require land area in metric units. Convert your acreage to m² (or hectares) for program applications and reporting.
