Convert Picomoles per day to Picomoles per hour
Convert Picomoles per day (pmol/d) to Picomoles per hour (pmol/h) instantly and accurately.
Conversion Formula
pmol/h = pmol/d × 0.04166666667
About Picomoles per day
The picomole per day (pmol/d) equals 10⁻¹²/86400 ≈ 1.157×10⁻¹⁷ mol/s, applied in clinical biomarker assays for trace hormones and in isotope-dilution pharmacokinetics. Testosterone circulating at very low concentrations (< 5 pmol/L) with a plasma clearance of 5 L/d yields urinary excretion on the pmol/d scale. 1 pmol/d ≈ 1.157×10⁻¹⁷ mol/s.
About Picomoles per hour
The picomole per hour (pmol/h) equals 10⁻¹²/3600 ≈ 2.778×10⁻¹⁶ mol/s, used in dermal permeability studies and slow-release pharmaceutical patch bioavailability tests. Passive diffusion of steroid hormones through biological membranes is quantified at pmol/h per cm² of membrane area. 1 pmol/h ≈ 2.778×10⁻¹⁶ mol/s.
