血糖换算器
在 mg/dL 和 mmol/L 之间换算血糖值，附正常范围参考。
Reference ranges
| Status | mg/dL | mmol/L | ||
|---|---|---|---|---|
| Fasting | 2h post-meal | Fasting | 2h post-meal | |
| Normal | 70–99 | < 140 | 3.9–5.5 | < 7.8 |
| Pre-diabetes | 100–125 | 140–199 | 5.6–6.9 | 7.8–11.0 |
| Diabetes | ≥ 126 | ≥ 200 | ≥ 7.0 | ≥ 11.1 |

血糖水平的单位因国家而异：美国等部分国家使用 mg/dL（毫克/分升），而欧洲、加拿大、澳大利亚及大多数国家使用 mmol/L（毫摩尔/升）。在阅读国际医学文献、使用进口血糖仪或与海外医疗人员沟通时，单位换算至关重要。
mg/dL 换算为 mmol/L 需除以 18.018；mmol/L 换算为 mg/dL 需乘以 18.018。例如，空腹血糖 100 mg/dL 约等于 5.6 mmol/L。本工具可即时完成双向换算，并显示临床重要阈值参考表。
正常空腹血糖通常低于 100 mg/dL（5.6 mmol/L）。100～125 mg/dL（5.6～6.9 mmol/L）提示糖尿病前期；两次测量均达到 126 mg/dL（7.0 mmol/L）或以上通常可诊断为糖尿病。
