About Pound per hour (lb/hr)

An imperial mass-flow unit dominant in US HVAC, boiler and steam-engineering work, petroleum refining, and chemical process plants. Boiler capacities in the US are traditionally rated in lb/hr of steam output (e.g., "500 horsepower boiler" ≈ 17,250 lb/hr of saturated steam). Fuel consumption on large engines and turbines is frequently quoted in lb/hr.

About Kilogram per hour (kg/hr)

A metric mass-flow unit used for industrial process streams, boiler steam output, refinery throughput, and bulk material handling. Chemical plant material balances are routinely computed in kg/hr. A steam boiler might produce 10,000 kg/hr; an espresso machine steam wand is ~15 kg/hr of steam. Converting kg/hr to lb/hr (×2.205) is common for US/international equipment comparison.

Understanding Pounds per hour

The Pound per hour (symbol: lb/hr) is a unit of mass flow rate. An imperial mass-flow unit dominant in US HVAC, boiler and steam-engineering work, petroleum refining, and chemical process plants. Boiler capacities in the US are traditionally rated in lb/hr of steam output (e.g., "500 horsepower boiler" ≈ 17,250 lb/hr of saturated steam). Fuel consumption on large engines and turbines is frequently quoted in lb/hr.

It belongs to the imperial measurement system.

Pounds per hour are commonly used in chemical processing, fuel systems, and environmental monitoring.

Understanding Kilograms per hour

The Kilogram per hour (symbol: kg/hr) is a unit of mass flow rate. A metric mass-flow unit used for industrial process streams, boiler steam output, refinery throughput, and bulk material handling. Chemical plant material balances are routinely computed in kg/hr. A steam boiler might produce 10,000 kg/hr; an espresso machine steam wand is ~15 kg/hr of steam. Converting kg/hr to lb/hr (×2.205) is common for US/international equipment comparison.

It belongs to the metric measurement system.

Kilograms per hour are commonly used in chemical processing, fuel systems, and environmental monitoring.

Why Convert Pounds per hour to Kilograms per hour?
