Volume Flow Rate Converter - m³/s to kg/s Calculator

How to Convert Volume Flow Rate

The Volume Flow Rate Converter calculates the equivalent flow rate between cubic meters per second (m³/s) and kilograms per second (kg/s) for water, using the following conversion factors (assuming water density = 1000 kg/m³):

From m³/s to kg/s:

\( \text{Flow Rate (kg/s)} = \text{Flow Rate (m}^3\text{/s)} \times 1000 \)

From kg/s to m³/s:

\( \text{Flow Rate (m}^3\text{/s)} = \text{Flow Rate (kg/s)} \times 0.001 \)

Where:

  • \( \text{m}^3\text{/s} \): Cubic meters per second, a volumetric flow rate unit.
  • \( \text{kg/s} \): Kilograms per second, a mass flow rate unit for water (density = 1000 kg/m³).

Enter the flow rate and select the unit to convert between m³/s and kg/s.

Using the Volume Flow Rate Converter

This converter is designed to assist with converting flow rates between m³/s and kg/s for water, useful in fields like fluid dynamics, engineering, and hydrology.

Input the flow rate value and select the unit (m³/s or kg/s). The calculator will display the converted values in both units.

Example: Convert 0.2 m³/s to kg/s.


  1. Flow Rate: \( 0.2 \, \text{m}^3\text{/s} \)
  2. Conversion: \( 0.2 \times 1000 = 200.00 \, \text{kg/s} \)
  3. Result: \( 0.2 \, \text{m}^3\text{/s} = 200.00 \, \text{kg/s} \)

Use this tool for quick and accurate conversions in engineering and scientific applications. Note: This assumes standard water density (1000 kg/m³); results may vary for other fluids.
