1 cubic metre per second (m³/s) equals 60000 litre per minute (L/min).

How it works

  • Expressed the source unit in cubic metre per second using its exact factor.
  • Divided by the target unit expressed in cubic metre per second.
  • Rounded the result to 12 significant digits.

1 m3_s = 60000 l_min
  • Both units measure volumetric flow rate, so the conversion is a single exact multiplication.

Methodology

  1. Express every unit as an exact factor to the cubic metre per second base.
  2. Multiply the input by the source factor and divide by the target factor.
  3. Round the result to 12 significant digits so a convert-then-convert-back operation stays within floating-point tolerance.

Usage

  1. Enter the value to convert.
  2. Choose the source and target units.
  3. Read the converted value and the conversion formula.

Limitations

Exact volumetric flow rate factors

Every volumetric flow rate unit is defined as an exact multiple of the cubic metre per second, so the conversion is a single multiplication with no approximation beyond floating-point representation.

Frequently asked questions

Which volumetric flow rate units does this converter support?
It supports every unit listed in the From and To menus, each expressed as an exact factor to the cubic metre per second.
Why does the result show a formula?
The formula shows the exact multiplication so you can verify the volumetric flow rate conversion by hand.
