How to use Flow Rate Converter
- Enter the flow rate and its source unit.
- Choose the destination unit and enter kg/m³ density if switching between mass and volume.
- Convert and check the time unit and gallon convention.
Example: Flow Rate Converter
Convert a volume flow to mass flow.
You add
Value: 60 L/min. To: kg/s. Density: 1000 kg/m³.
You get
The result is 1 kg/s.
Options
- Fluid density and gallon system
- Crossing from volume flow to mass flow uses entered density. Within volume units, distinguish US liquid gallons from imperial gallons.
- Decimal places
- Review small flow values in the destination volume-per-time unit before choosing 0, 2, 4, 6 or 8 decimal places. A rounded zero can hide a nonzero flow.
Supported inputs and limits
Constant-density conversion only. US liquid and imperial gallons are separate choices. No pipe geometry, pressure loss, pump sizing, gas standard-condition adjustment or changing-density model is included. Values accept at most 64 characters, 40 significant digits, 20 fractional places and magnitude 10¹⁸. Scientific notation has at most two exponent digits. Display rounding offers 0, 2, 4, 6 or 8 decimal places; small nonzero results stay visible.

Mass flow needs a material assumption
Sixty litres per minute is 0.001 m³/s. Multiplying by a density of 1000 kg/m³ gives 1 kg/s. For gases, use density and volume expressed for compatible pressure and temperature conditions.
Questions about Flow Rate Converter
Can litres per minute become kilograms per second directly?
A density is needed. The tool converts volume per time to mass per time by multiplying by the entered density.
How do I choose a gallon-based flow unit?
The selected unit names US liquid or imperial explicitly. They have different volumes; use the one stated by your source.
Can this size a pump or pipe?
No. Those calculations need operating conditions and system geometry beyond a unit conversion.
