Our kilogram per second to pound 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 Second and pounds per second 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 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. [2]
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.
When converting mass flow rate between kilograms per second (kg/s) and pounds per second (lb/s), keep full floating-point precision (1 kg/s = 2.2046226 lb/s; 1 lb/s = 0.4535924 kg/s) during intermediate calculations and round only the final pound per second figure to match your instrument tolerance.
