Convert one inch to centimetres
Input and settings
Category: length / From: inch / To: cm / Value: 1
Expected result
2.54 cm
Unit Converter
Convert length, weight, temperature, area, volume, and speed with defined constants.
How to use
These are example steps; replace the values for your task.
- Select Length and enter 10.
- Choose inch as the source and cm as the target.

Result
Convert only compatible measurements
Choose length, weight, temperature, area, volume, or speed first. The From and To lists then show only units in that category—for example, miles to kilometres or Fahrenheit to Celsius.
The conversion keeps full precision internally and formats the displayed result. US cups and fluid ounces use US customary definitions, so they are not treated as Imperial measures.
About this tool
Convert six common types of measurement. Changing category limits the unit lists to compatible measurements.
Cup and fl oz use US customary definitions. Weight and volume are not converted between each other because that would require the material's density.
Try a use case and check the result
Compare a length conversion with a temperature conversion that also changes the reference point.
Example buttons replace the inputs and settings above and calculate. Restore previous input steps back one example at a time. After trying multiple examples, repeat restore to return to your original input. This history is lost when the page closes.
Convert 32°F to 0°C
Input and settings
Category: temperature / From: °F / To: °C / Value: 32
Expected result
0 °C
How to read the result
Length uses the factor 1 inch=2.54 cm. Temperature has a different zero point, so simply multiplying 32 by a factor does not give 0°C. Check the output unit together with the original value shown below it.
Scope and limits
The options cover length, mass, temperature, area, volume and speed. Cup and fl oz use US units. Temperatures below absolute zero are rejected. Currency, compound units and unit names inside the value are not parsed. Arithmetic uses floating-point numbers with at most ten displayed decimal places.
Verification: existing convertUnit checks cover 1 inch→2.54 cm, 32°F→0°C and rejection below absolute zero. Restoration includes unit choices rebuilt when the category changes.

Convert inches to centimetres
In Length, converting 10 inch to cm gives 25.4 cm.
The value is converted through a common reference unit. Temperature also requires an offset, not just a scale factor.
Each category provides units of the same quantity. Check the unit shown beside the result after changing selections.
Frequently asked questions
Which cup definition is used?
The volume category uses the US cup, approximately 236.588 mL.
Does temperature conversion check absolute zero?
Yes. Values below absolute zero are rejected.
Are conversion constants rounded?
Defined conversion constants are used internally; only the displayed result is formatted.
