How to Convert Liters per Second to Liters per Hour
To convert liters per second to liters per hour, multiply the flow rate by the following conversion ratio: 3,600 liters per hour/liters per second.
Since one liters per second is equal to 3,600 liters per hour, you can use this simple formula to convert:
The flow rate in liters per hour is equal to the flow rate in liters per second multiplied by 3,600.
For example, here's how to convert 5 liters per second to liters per hour using the formula above.
How Many Liters per Hour Are in a Liters per Second?
There are 3,600 liters per hour in a liters per second, which is why we use this value in the formula above.
Our liters per second to liters 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 liters per hour 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 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. [2]
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.
When converting flow rate between liters per second (L/s) and liters per hour (L/h), keep full floating-point precision (1 L/s = 3,600 L/h; 1 L/h = 0.000277778 L/s) during intermediate calculations and round only the final liters per hour figure to match your instrument tolerance.
