Convert glucose units accurately with clear UK and US outputs. See charts, tables, and targets. Make safer logging decisions using consistent unit conversions daily.
| mmol/L | mg/dL | Common note |
|---|---|---|
| 4.0 | 72.1 | Lower typical fasting area |
| 5.5 | 99.1 | Upper typical fasting area |
| 7.8 | 140.5 | Often used post-meal threshold |
| 10.0 | 180.2 | Clearly elevated reading |
| 13.9 | 250.5 | High reading needing attention |
US to UK: mmol/L = mg/dL ÷ 18.0182
UK to US: mg/dL = mmol/L × 18.0182
The factor 18.0182 converts concentration units for glucose between milligrams per deciliter and millimoles per liter.
The UK commonly reports blood glucose in mmol/L, while the US usually reports mg/dL. Both describe the same concentration, but the number format changes because the measurement unit changes.
This calculator uses 18.0182. Multiply mmol/L by 18.0182 to get mg/dL. Divide mg/dL by 18.0182 to get mmol/L.
Yes. The conversion itself stays identical. The context setting only changes the reference note and interpretation wording shown with your result.
No. It converts units and shows general reference notes. Diagnosis depends on clinical testing, timing, symptoms, and professional assessment.
Meters, timing, meals, stress, illness, and lab methods can create differences. Always compare readings using the same unit system and the same timing context.
This page flags values below 70 mg/dL as low. That is a general safety marker, but your personal action threshold may differ based on medical advice.
They save the displayed result table, including both converted units, your chosen context, interpretation note, and reference message for easy sharing or logging.
No. The graph creates nearby sample points around your entered value to help visualize equivalent glucose levels in both unit systems.
