How to Convert Pounds per Hour to Kilograms per Hour

To convert pounds per hour to kilograms per hour, multiply the mass flow rate by the following conversion ratio: 0.4535924 kilograms per hour/pound per hour.

Since one pound per hour is equal to 0.4535924 kilograms per hour, you can use this simple formula to convert:

kilograms per hour = pounds per hour × 0.4535924

The mass flow rate in kilograms per hour is equal to the mass flow rate in pounds per hour multiplied by 0.4535924.

For example, here's how to convert 5 pounds per hour to kilograms per hour using the formula above.

kilograms per hour = (5 lb/h × 0.4535924) = 2.2679619 kg/h

How Many Kilograms per Hour Are in a Pound per Hour?

There are 0.4535924 kilograms per hour in a pound per hour, which is why we use this value in the formula above.

1 lb/h = 0.4535924 kg/h|1 kg/h = 2.2046226 lb/h

Our pound per hour 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 Hour 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 Hour?

A pound per hour is a unit of mass flow rate equal to 0.000125998 kilograms per second (kg/s), the base unit for mass flow rate. Steam boiler and aviation fuel flow unit. [1]

The pound per hour is classified as a US customary unit of mass flow rate. Pounds per Hour can be abbreviated as lb/h; for example, 1 pound per hour can be written as 1 lb/h.

When working with pounds per hour (lb/h) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.

In practice, pounds per hour (lb/h) are widely used across fine-tolerance laboratory, analytical, and micro-scale mass flow rate measurements 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 hour (lb/h) and kilograms per hour (kg/h), keep full floating-point precision (1 lb/h = 0.4535924 kg/h; 1 kg/h = 2.2046226 lb/h) during intermediate calculations and round only the final kilogram per hour figure to match your instrument tolerance.
