SHBG Unit Converter
Sex Hormone-Binding Globulin (SHBG) is a glycoprotein produced by the liver that binds tightly to testosterone, dihydrotestosterone (DHT), and estradiol. It regulates the availability of these sex hormones to body tissues.
SHBG levels are critical for calculating the **Free Androgen Index (FAI)** and assessing conditions such as PCOS, hypogonadism, and thyroid disorders. This converter facilitates switching between the standard SI unit (nmol/L) and mass units (µg/mL).
SI Units / Molar
RecommendedNanomoles per liter (International Standard).
Mass Units
Clinical Context
Reference Ranges (Adults):
• Men: 10 – 57 nmol/L.
• Women: 18 – 144 nmol/L.
Interpretation:
• High SHBG: Hyperthyroidism, pregnancy, anorexia, liver disease.
• Low SHBG: Obesity, PCOS, hypothyroidism, type 2 diabetes.
Conversion Logic:
Based on Molecular Weight ~95,000 Da (95 kDa).
1 nmol/L ≈ 0.095 µg/mL (mg/L).
1 µg/mL ≈ 10.53 nmol/L.

Frequently Asked Questions
nmol/L is the preferred SI unit for SHBG because it reflects the molar binding capacity for sex hormones, which is physiologically more relevant than mass.
Yes. 1 microgram per milliliter is numerically identical to 1 milligram per liter.
