About Cubic Meter / Second and Liter / Second

Cubic Meter / Second (m³/s)

Cubic meters per second is the SI unit of volumetric flow.

Where it's used: River discharge, dam turbine capacity, and HVAC air volumes.

Liter / Second (L/s)

Liters per second measures larger volumetric flows.

Where it's used: Rivers, water treatment, and industrial pumping systems.

m³/s to L/s Formula and Examples

Direct Formula L/s = m³/s × 1000

Inverse Formula m³/s = L/s × 0.001

Mental Math Shortcut

Multiply the value by roughly 1000 to calculate the equivalent amount in your head.

Common Cubic Meter / Second to Liter / Second Calculations

5 m³/s = 5000 L/s
10 m³/s = 10000 L/s
50 m³/s = 50000 L/s
100 m³/s = 100000 L/s
500 m³/s = 500000 L/s

Precision & Practical Use

For example, 10 m³/s = 10000 L/s — roughly multiple unit increments.

Results are computed to up to 9 decimal places. Round to the precision of your measuring instrument — for most flow rate applications, 2–3 significant figures are plenty.

Flow rate calculations measure fluid velocity, expressing volume per unit time. Typically calculated in Gallons per Minute (GPM) or Liters per Minute (LPM), these measurements are fundamental in plumbing, irrigation, and hydraulic system design.

Sizing a water pump or designing a sprinkler system requires translating fluid flow rates across metric and imperial systems. Flow calculators allow plumbers and civil engineers to determine if piping and valve sizes can handle specific GPM or LPM rates under pressure, optimizing fluid transport systems for peak output.

How to Convert Cubic Meter / Second to Liter / Second

How many liter / seconds are in one cubic meter / second?

One Cubic Meter / Second (m³/s) equals 1000 Liter / Second (L/s). To convert cubic meter / seconds to liter / seconds, multiply the cubic meter / second value by 1000.

How do I convert Cubic Meter / Second to Liter / Second?

Multiply your cubic meter / second value by 1000 to get the result in Liter / Second: L/s = m³/s × 1000. For example, 5 m³/s = 5000 L/s.

What is the formula for converting m³/s to L/s?

The conversion formula is L/s = m³/s × 1000. Use the calculator above for any value, and see the reference table below for common inputs from 0.001 to 1000.
