Formula
Linear: converted = value × (toFactor / fromFactor) Temperature: °F = (°C × 9/5) + 32 °C = (°F − 32) × 5/9 K = °C + 273.15
FAQs
Temperature conversion?
Temperature needs an offset: °F = (°C × 9/5) + 32 and K = °C + 273.15.
Precision?
Use more decimals for scientific work and fewer for everyday use. This converter includes decimal control.
Units list?
Common SI and imperial units are included across multiple categories.
Compound units?
Speed and energy include common compound units like mph and kWh with standard definitions.
Custom units?
For linear conversions, you can enter a custom factor (value × factor). Temperature needs a formula (offset + scale).
