Use density in kg/L. Water is approximately 1 kg/L.

Overview

LPM to kg/s

LPM to kg/s converts liters per minute into kilograms per second using fluid density. Entities include density, specific gravity, water, fuel, oil, liquids, SI units, mass flow rate, Coriolis meters, pumps, and process piping.

Calculator

LPM to kg/s Calculator

The LPM to kg/s calculator uses water-like density by default. For fuel, oil, chemicals, or process liquids, use the actual density in kg/L.

Convert

Convert LPM to kg/s

To convert LPM to kg/s, multiply LPM by density in kg/L and divide by 60.

Unit Meaning

Liters Per Minute to kg/s

Liters per minute to kg/s changes volumetric flow into mass flow. This requires density because one liter of water, fuel, oil, or solvent can have a different mass.

Method

How to Convert LPM to kg/s

1

Find LPM.

2

Find density in kg/L.

3

Multiply LPM by density.

4

Divide by 60 to get kg/s.

Calculation

How to Calculate kg/s from LPM

kg/s = LPM x density / 60

For water, density is about 1 kg/L.

Quick Value

How Many kg/s in 1 LPM?

For water, 1 LPM = 0.016667 kg/s. For diesel, gasoline, oil, or other liquids, multiply by the actual density ratio.

Formula

LPM to kg/s Formula

kg/s = LPM x density kg/L / 60

Water estimate: kg/s = LPM / 60.

Mass Flow

Mass Flow Rate from LPM

Mass flow rate from LPM is used in process engineering, heat transfer, fuel systems, cooling loops, dosing systems, and material balance calculations.

Mass Flow

LPM to Mass Flow Rate

LPM to mass flow rate requires density. Coriolis meters measure mass flow directly, while many rotameters and magnetic flow meters measure volume flow.

kg/s

LPM to kg Per Second

LPM to kg per second is the same as LPM to kg/s and is common in SI engineering calculations.

Water

LPM to kg/s for Water

For water near standard conditions, density is approximately 1 kg/L, so 60 LPM is about 1 kg/s.

Fuel

LPM to kg/s for Fuel

LPM to kg/s for fuel depends on fuel density. Diesel, gasoline, kerosene, and fuel oil should use manufacturer or lab density data.

Liquids

LPM to kg/s for Liquids

For liquids such as water, oil, glycol, solvent, or chemicals, use density or specific gravity at operating temperature.

Reverse

kg/s to LPM

LPM = kg/s x 60 / density

Use density in kg/L.

Conversion

Mass Flow Rate Conversion

Mass flow rate conversion connects kg/s, kg/min, kg/hr, lb/hr, and volumetric units such as LPM when density is known.

FAQ

LPM to kg/s Questions

What does the LPM to kg/s calculator convert?

It converts liters per minute into kilograms per second for water, fuel, liquids, process flow, pump flow, and mass-balance calculations.

What is the LPM to kg/s formula?

Use kg/s = LPM x density in kg/L / 60. For water at about 1 kg/L, kg/s = LPM / 60.

How many kg/s are in 1 LPM?

For water, 1 LPM equals about 0.016667 kg/s. Other liquids depend on density.

Can I use this for fuel?

Yes, but use the correct fuel density. Diesel, gasoline, kerosene, and oil have different densities.

Is LPM to kg/s a mass flow rate conversion?

Yes. It converts volumetric flow to mass flow using fluid density.

Can I convert kg/s back to LPM?

Yes. Use LPM = kg/s x 60 / density in kg/L.

Which entities matter for liquid mass flow?

Important entities include density, specific gravity, water, diesel, oil, pumps, Coriolis meters, process piping, ISO, and SI units.
