Flow Converter (Mass)

About This Tool

This Mass Flow Rate Converter is a vital tool for chemical and process engineering, aerospace, and any field dealing with compressible fluids like gases. It converts units of mass flow rate, which measures the mass of a substance that passes per unit of time. The base unit is the kilogram per second (kg/s).

Unlike volumetric flow rate, mass flow rate is independent of changes in temperature and pressure, making it a more reliable measure for gases and fluids with variable density. This tool is essential for managing chemical reactions, fuel consumption, and material transfer processes.

Tips & Features

• Why Mass Flow? When the density of a fluid changes (e.g., air being compressed), its volume changes, but its mass remains constant. Mass flow rate provides an unambiguous measure of how much 'stuff' is moving through a system.
• Common Industrial Units: While the SI unit is kg/s, many industrial processes use more practical units like pounds per hour (lb/h) or metric tons per hour (t/h) for material balance calculations.
• Conversion from Volumetric Flow: You can calculate mass flow rate by multiplying the volumetric flow rate by the fluid's density (Mass Flow = Volume Flow × Density).
