Conversion Formula

t/s = lb/min × 7.559872833e-6

About Pounds per minute

The pound per minute (lb/min) equals 0.45359237/60 ≈ 7.560×10⁻³ kg/s, the standard unit for US fire-suppression system design (sprinkler flow demand) and HVAC hydronic loop balancing. A fire-sprinkler head at 15 psi discharges roughly 30-40 lb/min of water; industrial humidifiers are rated in lb/min of steam. 1 lb/min ≈ 7.560×10⁻³ kg/s = 60 lb/h.

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.
