Your inputs

US and UK gallons per minute differ by about 20 percent, so the labels keep them separate. Actual flow in a pipe also depends on pressure and diameter, which this converter does not model.

What you can do with this tool

How it works

Result = input × source-unit factor ÷ destination-unit factor. All factors are relative to the same base unit; intermediate values are not rounded.

Frequently asked questions

Which unit definitions are used?

Litres/second, Litres/minute, m³/hour, US gallons/minute, Cubic feet/minute, Cubic metres/second, UK gallons/minute. Read the labels carefully: regional or decimal/binary variants are separate choices.

What flow does a typical tap give?

Most bathroom taps deliver 5 to 8 litres a minute at normal pressure — roughly 0.1 litres per second, which is why litres per minute is the friendlier unit indoors.
