VOLUME FLOW WORKSPACE

Volumetric Flow Rate Converter

Convert a measured volumetric flow among cubic metres, litres, US gallons, and cubic feet per stated second, minute, or hour.

Conversion input

Convert an existing volume flow rate

Enter the flow reported by a meter, specification, or calculation. Select the complete numerator-and-time unit instead of converting its volume component alone.

Find a unit6 / 6

Filter by unit name, symbol, or code. Your current selections remain available.

Known value0 / 80

Enter a non-negative average or instantaneous magnitude and retain the source fluid conditions separately.

Convert from

Choose the unit attached to the value you entered.

Convert to

Choose the unit required for your report, estimate, or comparison.

Displayed precision

Choose the maximum decimal places shown. This does not increase source accuracy.

Conversion runs locally after the active reference catalogue loads.

What this tool delivers

Volumetric Flow Rate conversion contract

The page converts volume per time and never assumes that a tank volume is a rate or that volume flow equals mass flow.

What it converts

Converts supported SI, litre, US-gallon, and cubic-foot volume-flow units through cubic metres per second.

What you provide

A known flow magnitude, complete source unit, destination unit, fluid-condition context, and suitable precision.

What you receive

A selected flow equivalent, base-rate equation, complete unit table, and downloadable CSV.

Calculation method

How numerator volume and denominator time combine

Each factor converts both parts of the compound unit to cubic metres per second. Litre, US-gallon, and cubic-foot volumes use labelled definitions, while minute and hour denominators contribute 60- and 3,600-second factors before destination conversion.

Quick answers

Volumetric Flow Rate Converter questions

Is a US gallon per minute the same as an imperial gallon per minute?

No. This page labels and uses the US liquid gallon. An imperial gallon has a different volume, so substituting it would produce a material error. Confirm the meter, datasheet, and jurisdiction before conversion. If the source only says gpm without defining the gallon, resolve that ambiguity first.

Can I convert volumetric flow directly to mass flow?

Not from units alone. Mass flow equals volumetric flow multiplied by density, and density depends on the material and often temperature and pressure. For compressible gases, standard and actual volume-flow conventions also matter. Use a separate model with density measured or specified at conditions consistent with the source flow.

Does this result include pipe losses or pump performance?

No. It preserves one reported flow magnitude in another unit. Pressure loss, pump operating point, valve position, pipe roughness, fittings, elevation, viscosity, Reynolds number, and transient behavior require a hydraulic model and system data. Treat this conversion as an input normalization step, not an equipment-selection result.
