About Area Converter
Convert square units, acres and hectares.
Does this tool send my data anywhere?
No. Its calculation or transformation happens on your device.
Using Area Converter with the right inputs
Convert square units, acres and hectares. Start by matching your task to the quantities and options shown below. The definitions of the inputs matter as much as the final number or transformed output; retain the original values so that you can repeat or check the result.
Inputs and options explained
- Value: Enter the numeric value for this quantity using the units or scale shown in the label.
- From: choose Square metres (m²), Square kilometres (km²), Square centimetres (cm²), Square millimetres (mm²), Square feet (ft²), Square inches (in²), Square yards (yd²), Acres, Hectares.
- To: choose Square metres (m²), Square kilometres (km²), Square centimetres (cm²), Square millimetres (mm²), Square feet (ft²), Square inches (in²), Square yards (yd²), Acres, Hectares.
- Decimal precision: choose 2 decimal places, 4 decimal places, 6 decimal places, 8 decimal places, 10 decimal places.
Example to try in this tool
Use the following sample values to see how the controls and result fit together. They are an illustration of the operation, not recommended values for your own situation.
- Value: 1
- From: Square metres (m²)
- To: Square kilometres (km²)
- Decimal precision: 2 decimal places
Select Convert. The result begins with:
Square kilometres (km²)
0
1 Square metres (m²)
Square metres (m²)
1
This example records the tool’s output for those inputs. Check the method and assumptions against your own task before using a result; reproducing an example is not independent certification of the underlying model.
Interpretation and limitations
Use consistent length units throughout a calculation. Area is expressed in squared units and volume in cubed units. Distinguish a radius from a diameter and verify that the shape or coordinate system in your problem matches the measurements requested by the form.
Why is the unit of the result different from the input?
Area and volume combine multiple lengths, producing squared and cubed units respectively. Convert the full quantity with the correct power rather than changing only the unit label.
Before you use the output
- Choose the intended action: ⇄ Swap units, Convert. Re-run the operation after changing an input or mode so that you are checking the updated result.
- Read the result label and any accompanying explanation. Keep the input values or source file with the output so that a later comparison uses the same assumptions.
- If a result looks unexpected, check units, separators and selected options first. Try a smaller example you can verify rather than repeatedly changing several settings at once.
Questions or a result that needs checking?
If you find a discrepancy, report a problem with Area Converter. Include a non-sensitive example, the selected options, the result you expected and the result shown. This makes the issue easier to reproduce. See About & privacy for how the site handles tool inputs.
