Custom Unit Converter

Use a conversion factor you already know to move between any two linearly related custom units.

Custom conversion

Enter values to calculate

Use this tool only when the relationship between the two units is linear and can be represented by one multiplication factor.

Factor-based conversion

If 1 source unit equals F target units, then source value × F gives the target value.

Reverse conversion

The reciprocal factor converts in the opposite direction, provided the factor is greater than zero.

Linear relationships only

This custom tool is not suitable for conversions that need an offset or non-linear formula, such as Celsius to Fahrenheit or logarithmic scales.

Frequently asked questions

Does conversion happen in my browser?

Yes. These value conversions run in the browser and do not require an account.

Should I verify a critical conversion?

Yes. For engineering, laboratory, medical, financial, legal, or safety-critical work, verify the unit definition and result against an authoritative standard for your context.
