The temperature converter instantly converts between Celsius (°C), Fahrenheit (°F), and Kelvin (K) in both directions. Nurses use this tool to convert patient temperature readings between unit systems, interpret foreign medical records, and cross-reference equipment readings. Normal body temperature is 36.1–37.2°C (97–99°F); a fever is defined as ≥38°C (100.4°F); and hyperpyrexia — a medical emergency — begins at 41°C (105.8°F).
| Condition | Celsius | Fahrenheit |
|---|---|---|
| Severe hypothermia | <32°C | <89.6°F |
| Mild hypothermia | 32–35°C | 89.6–95°F |
| Normal | 36.1–37.2°C | 97–99°F |
| Low-grade fever | 37.3–38°C | 99.1–100.4°F |
| Fever | 38.1–39°C | 100.5–102.2°F |
| High fever | 39.1–41°C | 102.3–105.8°F |
| Hyperpyrexia | >41°C | >105.8°F |

37°C is equal to 98.6°F — this is the commonly cited average normal human body temperature. However, the normal range is 36.1–37.2°C (97–99°F), and individual baseline temperatures vary.
A fever is generally defined as a body temperature of 38°C (100.4°F) or above. A low-grade fever is 37.3–38°C. High fever is 39.1–41°C. Hyperpyrexia — above 41°C (105.8°F) — is a medical emergency requiring immediate intervention.
