Use this to calculate gravity and wort volume post boil. Use the **Boil off Rate calculator** below to work out your kit rate. The figure should be somewhere between
5-15%.

Use this to calculate your boil off percentage. This will work on any units as it's a percentage calculation.

Use this to calculate how much water evaporates during your boil.
Use the **kettle power factor** to tweak the results. If the amount
of water boiled off is less or more than the calculated figures, increase
or decrease the power factor to get the correct result.
