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

How to Convert Volume Flow Rate

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

From m³/hr to kg/hr:

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

From kg/hr to m³/hr:

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

Where:

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

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

Using the Volume Flow Rate Converter

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

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

Example: Convert 1.5 m³/hr to kg/hr.


  1. Flow Rate: \( 1.5 \, \text{m}^3\text{/hr} \)
  2. Conversion: \( 1.5 \times 1000 = 1500.00 \, \text{kg/hr} \)
  3. Result: \( 1.5 \, \text{m}^3\text{/hr} = 1500.00 \, \text{kg/hr} \)

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.
