How precise are the results?
We display up to 12 significant digits. Very small or large values use scientific notation. Floating-point arithmetic and rounded definitions can introduce small differences.
Does this work without JavaScript?

Can I convert between different families?
Only units of the same quantity can be converted directly. For example, converting liters to kilograms requires the material's density.
