Definitions and assumptions
Area factors are expressed relative to square metres. A length conversion factor is squared for area: one square foot is 0.09290304 square metres. Land-survey units use the conventions listed for each unit.
Frequently asked questions
how many m² is 1 mi²?
1 Square miles = 2,589,988.110336 Square metres. Auto mode preserves significant digits for small values; manual mode rounds to the selected decimal places. ≈ means approximate; < means below the display limit. Extreme values use × 10ⁿ. Calculations are rounded only for display.
how to convert mi² to m²?
The calculator converts the input to the category's reference unit, then divides by the target unit's factor. 1 × 2,589,988.11034 ≈ 2,589,988.110336 Square metres. Use the source and target factors shown in the formula. The worked example uses the value on this page, and the table provides other common values.
Can I use a length conversion factor directly for area?
No. Square the length factor when both dimensions change. For example, because one foot is 0.3048 metres, one square foot is 0.3048² square metres.
Why is the displayed result rounded?
Auto mode preserves significant digits for small values; manual mode rounds to the selected decimal places. ≈ means approximate; < means below the display limit. Extreme values use × 10ⁿ. Calculations are rounded only for display.
What input range can I use?
This calculator accepts non-negative values up to 1 trillion, with up to 8 decimal places. It does not calculate signed vectors or calendar date intervals.
Why is a unit unavailable?
A conversion is unavailable when a verified unit definition or a current exchange-rate value has not been configured. The tool does not invent a coefficient.
