Convert Milligrams per day to Metric tons per hour
Convert Milligrams per day (mg/d) to Metric tons per hour (t/h) instantly and accurately.
Conversion Formula
t/h = mg/d × 4.166666667e-11
About Milligrams per day
The milligram per day (mg/d) equals 10⁻⁶/86400 ≈ 1.157×10⁻¹¹ kg/s, used in toxicology (daily intake limits) and in slow-release pharmaceutical implants. WHO acceptable daily intake for food additives is expressed in mg/kg body mass per day; a 70 kg adult at 1 mg/kg/d represents a 70 mg/d dose. 1 mg/d ≈ 1.157×10⁻¹¹ kg/s.
About Metric tons per hour
The metric tonne per hour (t/h) equals 1 000/3600 ≈ 0.27778 kg/s, the dominant capacity unit in European and international process engineering. Equipment datasheets for conveyor belts, crushers, mills, dryers, compactors, and cyclone separators specify throughput in t/h. A 500 MW coal plant consumes ≈70-90 t/h of pulverised coal; a large rotary cement kiln produces ≈200-300 t/h of clinker. 1 t/h = 1 000/3600 kg/s ≈ 1.102 short ton/h.
