Frequently Asked Questions

Eight categories covering everyday and technical needs: length (mm to miles), weight (mg to tons and stone), temperature (Celsius, Fahrenheit, Kelvin), area (including acres and hectares), volume (ml to US gallons), speed (including knots), data (bits to terabytes), and time (ms to years).

Most conversions are simple multiplication, but temperature scales have different zero points — so Celsius to Fahrenheit is °F = °C × 9/5 + 32, not a plain ratio. The converter applies the correct formulas automatically.

US units — the gallon is the US gallon (3.785 liters), which differs from the imperial gallon (4.546 liters) used in the UK. Worth checking whenever a recipe or spec crosses the Atlantic.

Conversions use standard reference factors and display up to 8 decimal places, switching to exponential notation for very small values — precise enough for engineering homework and everyday use alike.
