Glucose Unit Converter
Glucose is the body’s main source of energy, derived primarily from the digestion of carbohydrates. Blood glucose levels are tightly regulated by the pancreatic hormones Insulin (which lowers glucose) and Glucagon (which raises glucose).
Glucose measurement is essential for diagnosing Diabetes Mellitus, prediabetes, and managing critical conditions like hypoglycemia (low sugar) and diabetic ketoacidosis (DKA). Standardized reporting is necessary to ensure consistent interpretation of diagnostic and therapeutic thresholds worldwide. This converter facilitates switching between the conventional mass unit (mg/dL) and the International SI unit (mmol/L).

Clinical Context
Diabetes Diagnosis (ADA Standards):
• Fasting Plasma Glucose (FPG): ≥ 126 mg/dL (≥ 7.0 mmol/L)
• Normal FPG: < 100 mg/dL
Hypoglycemia is generally defined as plasma glucose < 70 mg/dL. The conversion factor relies on MW 180.16 g/mol: 1 mmol/L ≈ 18.016 mg/dL.

Frequently Asked Questions & Tips
The factor is 18.016. 1 mmol/L = 18.016 mg/dL.
Yes. mg/dL (milligrams per deciliter) and mg% (milligrams per 100 milliliters) are numerically identical.
