October 15, 2026 · 3 min read
Normal body temperature is usually given as 37 °C (98.6 °F), but healthy people range from about 36.1 °C to 37.2 °C (97 °F to 99 °F). It is lower in the morning, higher in the evening, and depends on where you measure.
| Reading | °C | °F |
|---|---|---|
| Low (hypothermia) | below 35 | below 95 |
| Normal range | 36.1 – 37.2 | 97 – 99 |
| Low-grade fever | 37.5 – 38.2 | 99.5 – 100.8 |
| Fever | 38 and above | 100.4 and above |
| High fever | 39.4 and above | 103 and above |
These are general guidelines, not medical advice. For babies, older adults or anyone who seems very unwell, contact a doctor whatever the number says.
