What is unit conversion?
Unit conversion multiplies a measurement by the ratio of two unit definitions that share the same physical dimension. Temperature is different: Celsius, Fahrenheit, and Kelvin use offset formulas, not a simple scale factor.
Method
value_to = value_from × (factor_from ÷ factor_to)
Length/weight/volume use fixed SI factors (e.g. 1 in = 0.0254 m). Temperature: °C ↔ °F ↔ K via standard offset formulas. US gallon = 3.785411784 L.
Worked example — kg to lb
- Convert 70 kg to pounds.
- 1 kg = 2.2046226218 lb (approx from 0.45359237 kg per lb).
- 70 ÷ 0.45359237 ≈ 154.32 lb.
- ≈ 154.32 pounds
When this helps
- Recipe and shipping weight conversions
- Height/length for forms and DIY projects
- Weather °C ↔ °F while travelling
- Fuel or liquid volume between liters and US gallons
