Brew kettle evaporation calibration calculator

Calculate reference-temperature volume loss and observed evaporation with your own figures.

Your numbers

Use the units shown. Results update as you change valid inputs.

Use reference-temperature volume loss and observed evaporation to compare changes to your inputs. The method and limits below explain the scope.

Calculation method

Calculation method

Reference-temperature volume loss (L)

Adjusted loss=startVolume×startRatio-endVolume×endRatio; divide by elapsed time.

Observed evaporation (L/hour)

Adjusted loss=startVolume×startRatio-endVolume×endRatio; divide by elapsed time.

Symbols and units
a
Start measured volume (L)
b
End measured volume (L)
c
Elapsed boiling time (hours)
d
Start-volume conversion to reference-temperature ratio
e
End-volume conversion to reference-temperature ratio

Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.

Assumptions & limits

Assumptions & limits

  • Temperature conversion ratios user supplied; other transfers must be excluded from the measured loss. Supported limits: All required fields must be finite values of the exact declared type and within displayed bounds. Lists contain1–1000 finite numbers. JSON tables are numeric rectangular rows, at most100 rows and30 columns; individual tools have stricter shape/domain constraints. Temperature conversion ratios user supplied; other transfers must be excluded from the measured loss.
