About the All Units Converter
What is the All Units Converter?
Pick any two units from the same category and this all units converter converts between them.
It covers over 130 units in 14 categories and warns you if you mix categories, such as metres and kilograms.
How to use the All Units Converter
- Value (sample: 1)
- From (sample: Length – Foot (ft))
- To (sample: Length – Metre (m))
- Press Convert (results also refresh as you type). The result card shows the Converted Value, along with Result and Conversion factor.
Formula used
Result = Value × (base per from-unit) ÷ (base per to-unit)
Each category has an SI base unit; temperature has its own converter because it needs an offset.
Worked example
These are the sample values already filled in the calculator above, and the result it returns for them:

| Result | Value |
|---|---|
| Converted Value | 0.3048 m |
