How to Use This Calculator
  1. Enter your wearable-measured core body temperature (°C) and the current ambient temperature.
  2. Set your sensor accuracy rating (°C) — consumer wearables are typically ±0.2 °C.
  3. Select your current activity level and minutes since last exercise session.
  4. Enter the current hour of day (0–23) and menstrual cycle phase if applicable.
  5. Review the estimated skin temperature, deviation from baseline, and fever-likelihood confidence score.
