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 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 pounds per hour (lb/h) and pounds per second (lb/s), keep full floating-point precision (1 lb/h = 0.000277778 lb/s; 1 lb/s = 3,600 lb/h) during intermediate calculations and round only the final pound per second figure to match your instrument tolerance.
