How to Convert Liters per Hour to Liters per Second
To convert liters per hour to liters per second, multiply the flow rate by the following conversion ratio: 0.000277778 liters per second/liters per hour.
Since one liters per hour is equal to 0.000277778 liters per second, you can use this simple formula to convert:
The flow rate in liters per second is equal to the flow rate in liters per hour multiplied by 0.000277778.
For example, here's how to convert 5 liters per hour to liters per second using the formula above.
How Many Liters per Second Are in a Liters per Hour?
There are 0.000277778 liters per second in a liters per hour, which is why we use this value in the formula above.
Our liters per hour to liters per second calculator automatically converts your flow rate measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Liters per Hour and liters per second are both units used to measure flow rate. Keep reading to learn more about each unit.
What Is a Liters per Hour?
A liters per hour is a unit of flow rate equal to 1/60 of a liters per minute (0.0166667 L/min). Equal to 1/60 L/min. [1]
The liters per hour is classified as a metric and SI-compatible unit of flow rate. Liters per Hour can be abbreviated as L/h; for example, 1 liters per hour can be written as 1 L/h.
When working with liters per hour (L/h) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, liters per hour (L/h) are widely used across standard flow rate applications within SI metric workflows, engineering documentation, and technical data sheets.
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. [2]
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.
When converting flow rate between liters per hour (L/h) and liters per second (L/s), keep full floating-point precision (1 L/h = 0.000277778 L/s; 1 L/s = 3,600 L/h) during intermediate calculations and round only the final liters per second figure to match your instrument tolerance.
