How to Convert Kilograms per Hour to Kilograms per Second
To convert kilograms per hour to kilograms per second, multiply the mass flow rate by the following conversion ratio: 0.000277778 kilograms per second/kilogram per hour.
Since one kilogram per hour is equal to 0.000277778 kilograms per second, you can use this simple formula to convert:
The mass flow rate in kilograms per second is equal to the mass flow rate in kilograms per hour multiplied by 0.000277778.
For example, here's how to convert 10 kilograms per hour to kilograms per second using the formula above.
How Many Kilograms per Second Are in a Kilogram per Hour?
There are 0.000277778 kilograms per second in a kilogram per hour, which is why we use this value in the formula above.

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 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. [2]
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.
When converting mass flow rate between kilograms per hour (kg/h) and kilograms per second (kg/s), keep full floating-point precision (1 kg/h = 0.000277778 kg/s; 1 kg/s = 3,600 kg/h) during intermediate calculations and round only the final kilogram per second figure to match your instrument tolerance.
