About this conversion

Pressure conversions are used for tyre pressure (psi or bar), blood pressure readings in mmHg and weather maps in millibars.

Unit conversion is simply multiplication by a fixed ratio. The ratio between two units of the same quantity never changes, so once you know it you can convert any value in either direction.

For everyday use, three or four significant figures are usually enough. Engineering, science and trade documents may need more, and rounding should happen only at the end of a calculation.
