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 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.
