How to Convert Liters per Second to mL/h
To convert liters per second to ml/h, multiply the flow rate by the following conversion ratio: 3,600,000 ml/h/liters per second.
Since one liters per second is equal to 3,600,000 ml/h, you can use this simple formula to convert:
The flow rate in ml/h is equal to the flow rate in liters per second multiplied by 3,600,000.
For example, here's how to convert 5 liters per second to ml/h using the formula above.
How Many mL/h Are in a Liters per Second?
There are 3,600,000 ml/h in a liters per second, which is why we use this value in the formula above.
Our liters per second to milliliters per hour calculator automatically converts your flow rate measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Liters per Second and ml/h are both units used to measure flow rate. Keep reading to learn more about each unit.
What Is a Liters per Second?
A liters per second is a unit of flow rate equal to 60 liters per minute (L/min), the base unit for flow rate. Equal to 60 L/min. [1]
The liters per second is classified as a metric and SI-compatible unit of flow rate. Liters per Second can be abbreviated as L/s; for example, 1 liters per second can be written as 1 L/s.
When working with liters per second (L/s) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, liters per second (L/s) are widely used across standard flow rate applications within SI metric workflows, engineering documentation, and technical data sheets.
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. [2]
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.
When converting flow rate between liters per second (L/s) and ml/h (mL/h), keep full floating-point precision (1 L/s = 3,600,000 mL/h; 1 mL/h = 0.000000278 L/s) during intermediate calculations and round only the final milliliters per hour figure to match your instrument tolerance.
