LPM to kg/s Calculator

Flow Rate (LPM): Mass Flow Rate (kg/s):

1. What is an LPM to kg/s Calculator?

Definition: This calculator converts volumetric flow rate (liters per minute, LPM) to mass flow rate (kilograms per second, kg/s) using fluid density.

Purpose: It’s used in fluid dynamics, chemical engineering, and process design to calculate mass flow for various fluids.

2. How Does the Calculator Work?

The calculator uses this formula:

\dot{m} = Q \times ρ

Where:

$\dot{m}$ — Mass Flow Rate (kg/s)
$Q$ — Volumetric Flow Rate (m³/s), where $1 LPM = \frac{1}{60000} m³/s$
$ρ$ — Density (kg/m³, converted from input unit)

Explanation: Enter flow rate in LPM and fluid density in a chosen unit (kg/m³, kg/ft³, kg/cm³, kg/mm³, kg/in³). Density is converted to kg/m³, LPM to m³/s, and the mass flow rate is calculated.

3. Importance of Mass Flow Rate

Details: Mass flow rate is essential for material balance, pump sizing, and energy calculations across diverse fluid systems.

4. Using the Calculator

Tips: Input flow rate (≥0) and density (>0) with up to 5 decimal places (step=0.00001), and select a density unit. Results show LPM and kg/s.
