Blood sugar ranges for different conditions
| Item | Value |
|---|---|
| Low Blood Sugar Blood sugar level is too low, immediate sugar intake needed | < 70 mg/dL | < 3.9 mmol/L |
| Normal Fasting Fasting blood sugar within normal range | 70-99 mg/dL | 3.9-5.5 mmol/L |
| Impaired Fasting Blood sugar level is elevated, attention to diet and exercise needed | 100-125 mg/dL | 5.6-6.9 mmol/L |
| Diabetes (Fasting) Blood sugar level is too high, medical intervention required | ≥ 126 mg/dL | ≥ 7.0 mmol/L |
| Normal Post-meal Post-meal blood sugar within normal range | < 140 mg/dL | < 7.8 mmol/L |
| Diabetes (Post-meal) Post-meal blood sugar is too high, medical intervention required | ≥ 200 mg/dL | ≥ 11.1 mmol/L |

Supported inputs
| Input | Description |
|---|---|
| Blood Sugar Value | Enter a positive number |
| From Unit | Current unit of your blood sugar reading mg/dL (US, Japan) · mmol/L (UK, Canada, Australia) |
| To Unit | Desired unit for conversion mg/dL (US, Japan) · mmol/L (UK, Canada, Australia) |
| Meal Status | When the reading was taken relative to meals Fasting (before meal) · After meal (1-2 hours after) · Random (any time) |
Formula
mg/dL to mmol/L: mmol/L = mg/dL × 0.0555 mmol/L to mg/dL: mg/dL = mmol/L ÷ 0.0555 (Based on molecular weight of glucose ≈ 180.16 g/mol)
