How to Convert mL/h to m³/s

To convert ml/h to m³/s, multiply the flow rate by the following conversion ratio: 2.777778e-10 m³/s/milliliters per hour.

Since one milliliters per hour is equal to 2.777778e-10 m³/s, you can use this simple formula to convert:

m³/s = ml/h × 2.777778e-10

The flow rate in m³/s is equal to the flow rate in ml/h multiplied by 2.777778e-10.

For example, here's how to convert 5 ml/h to m³/s using the formula above.

m³/s = (5 mL/h × 2.777778e-10) = 1.388889e-9 m³/s

How Many m³/s Are in a Milliliters per Hour?

There are 2.777778e-10 m³/s in a milliliters per hour, which is why we use this value in the formula above.

1 mL/h = 2.777778e-10 m³/s|1 m³/s = 3,600,000,000 mL/h

Our milliliters per hour to cubic meters per second calculator automatically converts your flow rate measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.

mL/h and m³/s are both units used to measure flow rate. Keep reading to learn more about each unit.

What Is a Milliliters per Hour?

A milliliters per hour is a unit of flow rate equal to 1/60,000 of a liters per minute (0.000016667 L/min). Medical IV infusion pump rate unit. [1]

The milliliters per hour is classified as a metric and SI-compatible unit of flow rate. mL/h can be abbreviated as mL/h; for example, 1 milliliters per hour can be written as 1 mL/h.

In the metric system, "milli" is the standard SI prefix for thousandths, or 10⁻³. This makes the milliliters per hour (mL/h) a convenient decimal multiple of the liters per minute (L/min).

In practice, ml/h (mL/h) are widely used across fine-tolerance laboratory, analytical, and micro-scale flow rate measurements within SI metric workflows, engineering documentation, and technical data sheets.

What Is a Cubic Meters per Second?

A cubic meters per second is a unit of flow rate equal to 60,000 liters per minute (L/min), the base unit for flow rate. Coherent SI flow unit equal to 1,000 L/s (60,000 L/min). [2]

The cubic meters per second is classified as an International System of Units (SI) unit of flow rate. m³/s can be abbreviated as m³/s; for example, 1 cubic meters per second can be written as 1 m³/s.

When working with m³/s (m³/s) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.

In practice, m³/s (m³/s) are widely used across large-scale industrial, bulk, and macro-level flow rate specifications within International System of Units (SI) workflows, engineering documentation, and technical data sheets.

When converting flow rate between ml/h (mL/h) and m³/s (m³/s), keep full floating-point precision (1 mL/h = 2.777778e-10 m³/s; 1 m³/s = 3,600,000,000 mL/h) during intermediate calculations and round only the final cubic meters per second figure to match your instrument tolerance.
