Coffee Brew Volume Comparison

Compare measured output with your chosen reference, without inventing a universal pass/fail threshold.

Compare like-for-like measurements

Enter the same unit for every field. One reading is enough; three are optional. Zero is a valid observed output, not a reason to keep running a dry pump.

Unit

Your comparison volume

Observed output 1 Observed output 2 (optional) Observed output 3 (optional)

What the numbers mean

Average = sum of entered readings / number of entered readings. Difference (%) = (average / comparison volume - 1) x 100.

The tool does not convert a marketing "cup" into a volume, and it does not define a normal tolerance. Use your model's stated output or a clearly documented personal comparison.

Keep conditions consistent

Use the same drink, setting, coffee amount, container and measurement method. Coffee retained in grounds and programmed drink sizes can make unlike tests misleading.

Do not collect unsafe readings

Do not repeat a cycle with leakage, abnormal pump noise or no water supply. This calculator cannot establish that the machine is safe.
