Convert Pounds per hour to Metric tons per second
Convert Pounds per hour (lb/h) to Metric tons per second (t/s) instantly and accurately.
Conversion Formula
t/s = lb/h × 1.259978806e-7
About Pounds per hour
The pound per hour (lb/h) equals 0.45359237/3600 ≈ 1.260×10⁻⁴ kg/s, the dominant unit in US process engineering and steam-boiler rating. Packaged steam boilers are rated in lb/h of steam output (typical range 100-2 000 lb/h); HVAC cooling-coil latent loads are calculated in lb/h of moisture; flue-gas emission inventories are reported in lb/h per stack. 1 lb/h ≈ 1.260×10⁻⁴ kg/s.
About Metric tons per second
The metric tonne per second (t/s) equals 1 000 kg/s, the largest commonly cited mass-flow unit for catastrophic events and mega-scale engineering. The Chicxulub impactor released energy equivalent to removing ≈7×10¹¹ t of TNT over milliseconds; large submarine volcanic eruptions expel lava at 10³-10⁴ t/s. Industrial context: the Three Gorges Dam passes ≈45 000 m³/s of water = ≈45 000 t/s at peak flood. 1 t/s = 1 000 kg/s ≈ 1.102 short ton/s.
