About Pound per hour (lb/hr)

An imperial mass-flow unit (≈ 0.453592 kg/hr = 1.25998 × 10⁻⁴ kg/s). lb/hr is the universal working unit in US HVAC, steam engineering, petroleum refining, and chemical process plants. US boiler ratings are traditionally given in lb/hr of saturated steam output: a 'boiler horsepower' (BHP) is defined as 34.5 lb/hr of saturated steam at 212 °F per ASME PTC 4.1, so a '500 BHP boiler' produces 17,250 lb/hr. ASHRAE Handbook chapters on humidification, central plants, district heating, and refrigeration all use lb/hr. Refinery feed rates appear in lb/hr in older facility documentation (newer plants increasingly use kg/hr internationally and BPD for crude). Fuel consumption on large industrial engines, marine prime movers (with bunker fuel oil), and standby diesels is routinely quoted in lb/hr.

About Metric ton per hour (t/hr)

A metric mass-flow unit equal to 1,000 kg/hr ≈ 0.27778 kg/s. t/hr is the universal working unit for bulk-industrial mass-flow rates where kg/hr would produce awkwardly-large numbers. Reference applications: mining and quarrying conveyors per ISO 5048 and CEMA standards (a typical aggregate-belt conveyor 100-500 t/hr; a large iron-ore overland conveyor 5,000-10,000 t/hr), cement-kiln feed rates per CRH / Lafarge plant ratings (50-400 t/hr typical, world-record kilns 12,000 t/day = 500 t/hr), grain-handling and bulk-shiploading conveyors (a Panamax-class shiploader 2,000-3,000 t/hr), steel-mill billet and slab flow (modern continuous-caster 300-500 t/hr), wastewater-treatment-plant influent flow (large municipal WWTP 50-200 t/hr), and power-plant coal-feed systems (a 600 MW coal-fired unit ~200 t/hr at full load). Convert t/hr to kg/s by dividing by 3.6; to lb/hr by multiplying by 2,205.

Understanding Pounds per hour

The Pound per hour (symbol: lb/hr) is a unit of mass flow rate. An imperial mass-flow unit (≈ 0.453592 kg/hr = 1.25998 × 10⁻⁴ kg/s). lb/hr is the universal working unit in US HVAC, steam engineering, petroleum refining, and chemical process plants. US boiler ratings are traditionally given in lb/hr of saturated steam output: a 'boiler horsepower' (BHP) is defined as 34.5 lb/hr of saturated steam at 212 °F per ASME PTC 4.1, so a '500 BHP boiler' produces 17,250 lb/hr. ASHRAE Handbook chapters on humidification, central plants, district heating, and refrigeration all use lb/hr. Refinery feed rates appear in lb/hr in older facility documentation (newer plants increasingly use kg/hr internationally and BPD for crude). Fuel consumption on large industrial engines, marine prime movers (with bunker fuel oil), and standby diesels is routinely 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 Metric tons per hour

The Metric ton per hour (symbol: t/hr) is a unit of mass flow rate. A metric mass-flow unit equal to 1,000 kg/hr ≈ 0.27778 kg/s. t/hr is the universal working unit for bulk-industrial mass-flow rates where kg/hr would produce awkwardly-large numbers. Reference applications: mining and quarrying conveyors per ISO 5048 and CEMA standards (a typical aggregate-belt conveyor 100-500 t/hr; a large iron-ore overland conveyor 5,000-10,000 t/hr), cement-kiln feed rates per CRH / Lafarge plant ratings (50-400 t/hr typical, world-record kilns 12,000 t/day = 500 t/hr), grain-handling and bulk-shiploading conveyors (a Panamax-class shiploader 2,000-3,000 t/hr), steel-mill billet and slab flow (modern continuous-caster 300-500 t/hr), wastewater-treatment-plant influent flow (large municipal WWTP 50-200 t/hr), and power-plant coal-feed systems (a 600 MW coal-fired unit ~200 t/hr at full load). Convert t/hr to kg/s by dividing by 3.6; to lb/hr by multiplying by 2,205.

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

Why Convert Pounds per hour to Metric tons per hour?
