Dealing with blood glucose reports from different countries can be confusing due to varying measurement units. The Blood Glucose Unit Converter is designed specifically to convert between two medical standards: mmol/L (millimoles per liter) and mg/dL (milligrams per deciliter), using a fixed molecular weight coefficient for precise calculations. Simply input a blood sugar value in either unit, and the tool will automatically perform a real-time calculation based on the glucose molecular weight of 180.182 g/mol, applying the 18.0182 conversion factor.
Why is the conversion factor 18.0182?
This coefficient is derived from the relationship between the molecular weight of glucose (180.182 g/mol) and the unit volume conversion. It is the universally recognized standard for precise medical calculations.
Can the conversion results be used for medical diagnosis?
This tool provides reference values, but actual diagnoses must consider individual physiological indicators. For example, a fasting blood glucose of 5.5 mmol/L is approximately equal to 99 mg/dL. Please consult your doctor for specific clinical thresholds.
The tool only accepts numeric inputs; invalid entries will trigger an error prompt. Results are rounded to two decimal places, which may result in a ±0.01 deviation. When handling personal health data, we recommend disabling your browser's cache function.
For clinical purposes, it is recommended to use this alongside continuous glucose monitoring (CGM). When a continuous monitor displays 7.8 mmol/L, the corresponding US standard is 140 mg/dL, which is a key reference point for postprandial (post-meal) blood sugar control. Please note that different testing devices may have a systemic error of ±5%.
