FAQ
How accurate are the conversions?
Conversions use standard conversion factors and are accurate to at least 6 decimal places. Results are displayed with trailing zeros removed for readability.
Why is temperature conversion different from other units?
Temperature scales (Celsius, Fahrenheit, Kelvin) don't share a common zero point, so they require offset calculations rather than simple multiplication. For example, 0°C = 32°F = 273.15K.
Are the US measurements or Imperial measurements?
Volume measurements use US customary units (US gallon = 3.785 liters). Note that UK Imperial gallons are slightly larger (4.546 liters).
