Frequently asked questions
Which temperature scales are supported?
Celsius, Fahrenheit, and Kelvin. Temperature uses an offset so conversions are not simple multiplication.
What about US vs UK gallons?
Both are supported separately because a US gallon is ~3.79 L while an imperial gallon is ~4.55 L.
Does it support currency?
No. Currency rates change by the second and need a live feed. This tool focuses on physical units.
Is my input stored?
No. Conversions run locally and nothing is uploaded.
