How to Convert Kilograms per Hour to Pounds per Second
To convert kilograms per hour to pounds per second, multiply the mass flow rate by the following conversion ratio: 0.000612395 pounds per second/kilogram per hour.
Since one kilogram per hour is equal to 0.000612395 pounds per second, you can use this simple formula to convert:
The mass flow rate in pounds per second is equal to the mass flow rate in kilograms per hour multiplied by 0.000612395.
For example, here's how to convert 5 kilograms per hour to pounds per second using the formula above.
How Many Pounds per Second Are in a Kilogram per Hour?
There are 0.000612395 pounds per second in a kilogram per hour, which is why we use this value in the formula above.
Our kilogram per hour to pound per second calculator automatically converts your mass flow rate measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Kilograms per Hour and pounds per second are both units used to measure mass flow rate. Keep reading to learn more about each unit.
What Is a Kilogram per Hour?
A kilogram per hour is a unit of mass flow rate equal to 1/3,600 of a kilogram per second (0.000277778 kg/s). Process engineering mass flow unit. [1]
The kilogram per hour is classified as a metric and SI-compatible unit of mass flow rate. Kilograms per Hour can be abbreviated as kg/h; for example, 1 kilogram per hour can be written as 1 kg/h.
In the metric system, "kilo" is the standard SI prefix for thousands, or 10³. This makes the kilogram per hour (kg/h) a convenient decimal multiple of the kilogram per second (kg/s).
In practice, kilograms per hour (kg/h) are widely used across fine-tolerance laboratory, analytical, and micro-scale mass flow rate measurements within SI metric workflows, engineering documentation, and technical data sheets.
What Is a Pound per Second?
A pound per second is a unit of mass flow rate equal to 0.4535924 kilograms per second (kg/s), the base unit for mass flow rate. Equal to 0.453592 kg/s. [2]
The pound per second is classified as a US customary unit of mass flow rate. Pounds per Second can be abbreviated as lb/s; for example, 1 pound per second can be written as 1 lb/s.
When working with pounds per second (lb/s) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, pounds per second (lb/s) are widely used across standard mass flow rate applications within US customary workflows, engineering documentation, and technical data sheets.
When converting mass flow rate between kilograms per hour (kg/h) and pounds per second (lb/s), keep full floating-point precision (1 kg/h = 0.000612395 lb/s; 1 lb/s = 1,632.932532 kg/h) during intermediate calculations and round only the final pound per second figure to match your instrument tolerance.
