How to Convert Pounds per Second to Kilograms per Hour
To convert pounds per second to kilograms per hour, multiply the mass flow rate by the following conversion ratio: 1,632.932532 kilograms per hour/pound per second.
Since one pound per second is equal to 1,632.932532 kilograms per hour, you can use this simple formula to convert:
The mass flow rate in kilograms per hour is equal to the mass flow rate in pounds per second multiplied by 1,632.932532.
For example, here's how to convert 5 pounds per second to kilograms per hour using the formula above.
How Many Kilograms per Hour Are in a Pound per Second?
There are 1,632.932532 kilograms per hour in a pound per second, which is why we use this value in the formula above.
Our pound per second to kilogram per hour calculator automatically converts your mass flow rate measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Pounds per Second and kilograms per hour are both units used to measure mass flow rate. Keep reading to learn more about each unit.
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. [1]
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.
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. [2]
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.
When converting mass flow rate between pounds per second (lb/s) and kilograms per hour (kg/h), keep full floating-point precision (1 lb/s = 1,632.932532 kg/h; 1 kg/h = 0.000612395 lb/s) during intermediate calculations and round only the final kilogram per hour figure to match your instrument tolerance.
