Convert Grains per hour to Metric tons per second
Convert Grains per hour (gr/h) to Metric tons per second (t/s) instantly and accurately.
Conversion Formula
t/s = gr/h × 1.799969722e-11
About Grains per hour
The grain per hour (gr/h) equals 6.479891×10⁻⁵/3600 ≈ 1.800×10⁻⁸ kg/s, used in HVAC psychrometric calculations for dehumidifier capacity and moisture-removal rates. ASHRAE load calculation spreadsheets report latent loads in grains of water per hour; a typical residential dehumidifier removes 5×10⁵-2×10⁶ gr/h. 1 gr/h ≈ 1.800×10⁻⁸ 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.
