Common questions
Which gallons does the tool use?
US liquid gallons. One US gallon is 3.785411784 liters, not one UK imperial gallon.
Is Celsius converted with a multiplier?
No. The conversion incorporates the freezing-point offset, such as 0°C equaling 32°F.
Can I swap measurement units?
Yes. Swap changes the starting and destination units and lets you convert both directions.
