Summary
Convert length, mass, temperature, area, and volume units with deterministic factors.
Calculation details
Mass uses kilograms, grams, and pounds; temperatures below absolute zero are rejected. Calculations retain raw JavaScript number precision; display values are rounded to at most six decimal places.
Formula
Linear categories use value × source factor / target factor; temperature converts through Kelvin.
Worked example
Unit Converter example
1 kilometre equals 1,000 metres.
How it works
Pick a quantity category, enter a finite value, and choose source and target units. Temperature converts through Kelvin; other categories use deterministic factors.
Frequently asked questions
How accurate is the Unit Converter?
The calculation keeps raw numeric precision and rounds only the displayed result to at most six decimal places.
What should I do with an invalid result?
Check that every visible value is finite and that no required divisor is zero.
