Calculate your Glucose-Ketone Index instantly from a blood glucose and BHB ketone reading. No signup. Then track the trend over time in Keto Pro.
| GKI | Commonly described as |
|---|---|
| > 9 | No meaningful ketosis |
| 6 - 9 | Low-level ketosis |
| 3 - 6 | Moderate ketosis |
| 1 - 3 | High ketosis |
| < 1 | Deepest range discussed in therapeutic protocols |
Keto Pro logs every reading, charts your GKI over weeks, and exports a PDF you can hand to a clinician. Your data stays encrypted on your device.
Track this on Android →GKI is your blood glucose in mmol/L divided by your blood ketones (BHB) in mmol/L. It expresses glucose and ketones as a single ratio, which tracks metabolic state more tightly than either number on its own.
Divide your glucose reading in mg/dL by 18. A reading of 90 mg/dL is 5.0 mmol/L. This calculator does the conversion for you.
Ranges are commonly discussed as: above 9 (no meaningful ketosis), 6-9 (low-level), 3-6 (moderate), 1-3 (high), and below 1 (deepest). Appropriate targets depend entirely on your goal and your clinician's guidance.
Consistency matters more than timing. Most people test at the same time each day, commonly 2-3 hours after waking and before eating, so readings are comparable to each other.
