Specific Gravity, Volume, and Time Calculator

This page provides a calculator for determining specific gravity, volume, boil duration, and/or evaporation rate given other known values.

Enter values for parameters that are known. When possible, the unknown value(s) will be computed from the known values. You can undo a value by deleting it. Known values (inputs) are shown in black font. Computed values (outputs) are shown in a grayish-red font.

You can enter volume in either liters or gallons (or any other unit of measurement), and results will be displayed in the same units.

Parameters:

initial SG:		→	final SG:
initial volume:		→	final volume:
			boil duration:	minutes
			evaporation rate:	(volume-units per hour)
