Progesterone Unit Converter
Progesterone is a steroid hormone produced by the ovaries (corpus luteum) and placenta. It is essential for regulating the menstrual cycle and maintaining early pregnancy.
Clinically, progesterone levels are measured to confirm ovulation and assess the health of a pregnancy. This converter facilitates switching between the standard SI molar units (nmol/L) and conventional mass units (ng/mL, μg/L).
SI Units
RecommendedNanomoles per liter (International Standard).
Conventional Units
Clinical Context
Reference Ranges (Adult Female):
• Follicular Phase: < 1 ng/mL (< 3.18 nmol/L).
• Luteal Phase (Peak): > 10 ng/mL (> 31.8 nmol/L) typically indicates ovulation.
• Post-Menopause: < 0.5 ng/mL (< 1.6 nmol/L).
Conversion Logic:
Molecular Weight of Progesterone: 314.46 g/mol.
1 ng/mL ≈ 3.18 nmol/L.
1 nmol/L ≈ 0.314 ng/mL.

Frequently Asked Questions
Yes. 1 nanogram per milliliter is numerically identical to 1 microgram per liter.
Progesterone fluctuates significantly. A mid-luteal draw (Day 21 of a 28-day cycle) is standard to confirm ovulation.
