## How do I convert between units?

Converting multiplies the value by the exact factor between the two units, or applies the formula where the scales differ.

## Formula

Every unit converts through one defined base unit. Temperature uses custom scale-and-offset functions.

- Every unit converts through one defined base unit. Temperature uses custom scale-and-offset functions.
- Inputs used: Measurement, Value, From, To.
- Edge handling: Value is required.; Value must be at least -1e+300.; Value must be no more than 1e+300..

## Inputs

- Measurement
- Value
- From
- To

## Worked example: Metres to feet

Convert one metre to feet.
1. Start with Measurement: length, Value: 1, From: m, To: ft.
2. Apply the method: Every unit converts through one defined base unit. Temperature uses custom scale-and-offset functions.
3. Convert one metre to feet.

## Common questions

### How do I convert between units?

Converting multiplies the value by the exact factor between the two units, or applies the formula where the scales differ. Check the formula, example, and limitations on this page before using the result for a real conversions decision.

### Which measurements are supported?

Length, weight, temperature, speed, area, volume, and data storage. Check the formula, example, and limitations on this page before using the result for a real conversions decision.

### Are data units decimal or binary?

Both SI units such as GB and binary units such as GiB are available. Check the formula, example, and limitations on this page before using the result for a real conversions decision.

### How do I use the Unit Converter?

Enter the required values for Measurement, Value, From, To. The calculator applies the formula on this page and shows the main result with any supporting breakdown so you can check the arithmetic.

### What formula does the Unit Converter use?

Every unit converts through one defined base unit. Temperature uses custom scale-and-offset functions. The visible formula section above lists the calculation path and the edge cases the page handles, so the result can be checked without relying on the form alone.

### Can the Unit Converter be used for exact decisions?

Use it as a calculation aid, not as a substitute for checking the underlying rule, contract, policy, or professional advice that applies to your situation. When a result depends on local rules, personal details, prices, or dates, enter those values yourself and confirm them before acting.

## Limitations and assumptions

- Inputs outside the supported range are rejected rather than forced into a result.
- The result depends on the values you enter for this unit converter; it does not supply missing rates, rules, prices, dates, or assumptions for you.
