What is being measured?
Volumetric flow is volume per time. Converting it into mass flow requires a density under the applicable conditions.
US and imperial gallons differ. Barrels are US petroleum barrels of 42 US liquid gallons.
Meaning of imp gal/min
uk gallons per minute uses the symbol imp gal/min in this library and measures flow rate. Under the stated reference convention, 1 imp gal/min = approximately 0.0000757681666667 m³/s. This equivalence changes how a known value is written. It does not increase measurement accuracy or establish whether a measurement is appropriate to a real application.
Conversion method
Multiply the value by the source factor (0.00007576816666666667), then divide by the target factor (1). The factor ratio expresses the same flow rate measurement in the other unit.
Worked example
For a known value of 10 imp gal/min, the reference conversion gives 0.000757681666667 m³/s. Converting that result back gives approximately 10 imp gal/min. This reverse check helps catch a reversed factor, but matching round-trip arithmetic alone does not independently verify a source definition.

Precision and common mistakes
- Keep the source and target quantity consistent. A matching symbol is not enough to establish a compatible definition.
- Record the original measurement precision. Showing twelve significant digits in a table does not make a rounded input more precise.
- Check symbol capitalization, prefixes and any regional convention in the source. Use the displayed unit definition rather than a similarly named unit.
- Factors involving repeating fractions or π use finite numerical precision. Round the final answer to the precision justified by your input.
