How to Convert Kilograms per Hour to Grams per Second
To convert kilograms per hour to grams per second, multiply the mass flow rate by the following conversion ratio: 0.2777778 grams per second/kilogram per hour.
Since one kilogram per hour is equal to 0.2777778 grams per second, you can use this simple formula to convert:
The mass flow rate in grams per second is equal to the mass flow rate in kilograms per hour multiplied by 0.2777778.
For example, here's how to convert 5 kilograms per hour to grams per second using the formula above.
How Many Grams per Second Are in a Kilogram per Hour?
There are 0.2777778 grams per second in a kilogram per hour, which is why we use this value in the formula above.
Our kilogram per hour to gram 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 grams 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 Gram per Second?
A gram per second is a unit of mass flow rate equal to 1/1,000 of a kilogram per second (0.001 kg/s). Equal to 0.001 kg/s. [2]
The gram per second is classified as a metric and SI-compatible unit of mass flow rate. Grams per Second can be abbreviated as g/s; for example, 1 gram per second can be written as 1 g/s.
When working with grams per second (g/s) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, grams per second (g/s) 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 hour (kg/h) and grams per second (g/s), keep full floating-point precision (1 kg/h = 0.2777778 g/s; 1 g/s = 3.6 kg/h) during intermediate calculations and round only the final gram per second figure to match your instrument tolerance.
