Flow Rate Converter

About Flow Rate Converter

Flow rate is volume per unit time. Used in plumbing, HVAC, and fluid dynamics.

How to use this calculator

1. Choose the unit you have, such as \(\\text{m}^3/\\text{s}\) or \(\\text{L/s}\).
2. Enter the flow rate value into the converter.
3. Select the unit you want to convert to.
4. Read the converted result and check it against the formula.

The formula explained

The key relationship is \(1\\text{ m}^3/\\text{s} = 1000\\text{ L/s}\). That means one cubic meter per second is the same as one thousand liters per second, so you multiply or divide by \(1000\) to convert between them.

• \(\\\text{m}^3/\\text{s}\) = cubic meters per second, a measure of volume flow per second
• \(\\\text{L/s}\) = liters per second, a measure of volume flow per second
• \(1000\) = the conversion factor between \(\\text{m}^3/\\text{s}\) and \(\\text{L/s}\)

Step by step method

1. Start with the known flow rate and identify its unit.
2. Use \(1\\text{ m}^3/\\text{s} = 1000\\text{ L/s}\) to decide whether to multiply or divide by \(1000\).
3. Compute the converted value and attach the new unit.

Worked example

Problem. Convert \(2.5\\text{ m}^3/\\text{s}\) to \(\\text{L/s}\).

1. Use the conversion factor \(1\\text{ m}^3/\\text{s} = 1000\\text{ L/s}\).
2. Multiply \(2.5\) by \(1000\), so \(2.5\\text{ m}^3/\\text{s} = 2500\\text{ L/s}\).
3. The converted flow rate is \(2500\\text{ L/s}\).

Tips and common mistakes

• If you convert from \(\\text{m}^3/\\text{s}\) to \(\\text{L/s}\), multiply by \(1000\). If you convert the other way, divide by \(1000\).
• Keep track of the unit carefully, because a number like \(5\) can mean very different flow rates depending on whether it is \(\\text{m}^3/\\text{s}\) or \(\\text{L/s}\).
