How to Convert Kilograms per Second to Kilograms per Hour
To convert kilograms per second to kilograms per hour, multiply the mass flow rate by the following conversion ratio: 3,600 kilograms per hour/kilogram per second.
Since one kilogram per second is equal to 3,600 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 kilograms per second multiplied by 3,600.
For example, here's how to convert 10 kilograms per second to kilograms per hour using the formula above.
How Many Kilograms per Hour Are in a Kilogram per Second?
There are 3,600 kilograms per hour in a kilogram per second, which is why we use this value in the formula above.
Our kilogram 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.
Kilograms 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 Kilogram per Second?
SI unit of mass flow rate. It serves as a primary reference unit for measuring mass flow rate across scientific and practical applications. [1]
The kilogram per second is classified as an International System of Units (SI) unit of mass flow rate. Kilograms per Second can be abbreviated as kg/s; for example, 1 kilogram per second can be written as 1 kg/s.
As the primary coherent reference unit for mass flow rate in this category, all other mass flow rate units are mathematically anchored to the kilogram per second (kg/s).
In practice, kilograms per second (kg/s) are widely used across standard mass flow rate applications within International System of Units (SI) 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 kilograms per second (kg/s) and kilograms per hour (kg/h), keep full floating-point precision (1 kg/s = 3,600 kg/h; 1 kg/h = 0.000277778 kg/s) during intermediate calculations and round only the final kilogram per hour figure to match your instrument tolerance.
