Unit Converter
If you are not sure whether your task is about area, length, volume, or another unit family, start with the hub.
Length Converter
Area problems often start with width, height, or distance, so this is the natural next tool when you need to convert dimensions first.
Volume Converter
Rooms, tanks, fill volume, and material estimates often move from area into volume, so the two tools pair well.
Mass/Weight Converter
Coverage calculations often turn into weight calculations for materials, soil, feed, or bulk goods.
What area units mean in real-world use
Area measures the size of a flat surface. In the SI system, the standard unit is the square meter (m2), which is the area of a square that is 1 meter by 1 meter. Other units on this page, such as square feet, acres, hectares, mu, and square miles, are all just different ways of expressing area relative to square meters.
Area conversion works differently from length conversion because area is squared. If a length scales by 10, the area scales by 100. That is why 1 meter equals 100 centimeters, but 1 square meter equals 10,000 square centimeters. This is the main reason people misread area values when switching between metric and imperial units.
Metric area units range from very small values like square millimeters and square centimeters to larger land units like hectares and square kilometers. That makes them useful for everything from engineering sections and material coverage to farm plots and regional land totals.
Imperial and US customary area units are still widely used in property listings, construction, and land sales. Square feet are common for homes and offices, while acres are common for land and farms. If you work across countries or markets, moving between sq ft, acres, and m2 is often unavoidable.
Traditional Chinese land units such as fen, mu, and qing still appear in agricultural and land-management contexts. If you need to compare them with square meters, hectares, or acres, converting through a single standard unit keeps the math simple and the output consistent.
This page converts every value through square meters first, then into the target unit. Because area conversion is pure scaling, there is no offset term like there is in temperature conversion. Once the conversion factors are fixed, any supported pair of area units can be converted reliably.
Use Cases

- Standardize area units from different suppliers when comparing roofing, waterproofing, turf, or solar coverage
- Convert drawing or section values in mm2 and cm2 into m2 for a single calculation workflow
- Bring hectares, acres, mu, and square meters into one unit before budgeting a site, landscape, or public works project
- Compare warehouse, factory, showroom, and event-space measurements across square yards, square feet, and square meters
- Check km2, hectares, mu, and square miles when writing reports, studying geography, or preparing for exams

Which page should you use for area-related work?
Area, length, and volume often show up in the same workflow, but they solve different problems. Picking the right tool first makes everything faster.

Best Practices
Make sure you are converting area, not length or volume
m2, sq ft, acres, hectares, and mu are area units. mm, cm, m, and ft are length units. Liters, m3, and gallons are volume units. A lot of spreadsheets mix them together, so separating them first saves time.
Standardize to square meters before pricing or budgeting
Flooring, paint, membrane, insulation, turf, and cleaning work are often priced per square meter. Even if the original numbers come in as sq ft, acres, or mu, converting everything to m2 first makes totals and price comparisons much easier.
Use large-scale units for land and smaller units for buildings
A value can feel awkward if it is expressed at the wrong scale. Large parcels are easier to read in hectares, acres, or km2. Rooms, homes, and offices are easier to read in m2 or sq ft.
Use the square rule as a quick sense check
If a length doubles, the area should become four times larger. If a length is 10 times larger, the area should be 100 times larger. This is a fast way to catch obviously wrong conversions between m2 and cm2 or between ft2 and in2.
In property listings, check both the unit and what the area actually means
Unit conversion can tell you how sq ft, acres, m2, and hectares relate to each other, but it cannot tell you whether a listing means gross area, usable area, floor area, or lot area. For international property comparisons, you need both pieces.
FAQ
How many square feet are in 1 square meter?
1 square meter (m2) equals 10.7639 square feet (sq ft). This is one of the most common conversions for real estate listings, office rentals, and renovation estimates.
How many square meters are in 1 square foot?
1 square foot equals 0.092903 square meters. If you see a home or office listed in sq ft, multiply by 0.092903 to get the area in m2.
How many square meters are in 1 acre?
1 acre equals 4,046.8564 square meters. That is also about 0.4047 hectares, which makes acre-to-hectare conversion especially useful for land listings and farm plots.
How many mu are in 1 hectare?
1 hectare equals 15 mu. Since 1 mu equals 666.6667 square meters, a hectare works out to 10,000 square meters.
How many hectares are in 1 square kilometer?
1 square kilometer (km2) equals 100 hectares. It also equals 1,000,000 square meters and 1,500 mu, which is useful for larger sites, industrial parks, and land reports.
Why doesn’t area convert the same way length does?
Because area is squared. If a length becomes 10 times larger, the area becomes 100 times larger. That is why 1 m = 100 cm, but 1 m2 = 10,000 cm2.
What is the difference between square feet, square yards, and square inches?
1 square yard equals 9 square feet. 1 square foot equals 144 square inches. 1 square inch equals 0.00064516 square meters. These units often show up in construction, flooring, turf, and fabric measurements.
What standard does this page use for fen, mu, and qing?
It uses the modern standard for traditional Chinese land units: 1 fen = 66.6667 m2, 1 mu = 666.6667 m2, and 1 qing = 100 mu = 66,666.6667 m2.
Can this tool help with real estate area conversion?
Yes. It is useful when you need to convert between m2 and sq ft for homes, offices, retail units, or land listings. Just remember that unit conversion does not tell you whether a listing uses gross area, usable area, or lot area.
How accurate is the result?
The tool uses fixed conversion factors and double-precision math. Very small or very large results may be shown in scientific notation for readability, but the underlying conversion remains the same.
Can I see all area units at once?
Yes. Expand the results section to view the same number across all supported area units, grouped by system. It is handy for side-by-side comparison and quick reference.
Does this page upload my numbers?
No. Everything runs locally in your browser. Your input is not sent to a server and is not kept after you refresh or close the page.
