sci.heat-index Calculator
Calculates the apparent feels-like temperature from air temperature and relative humidity using the Steadman heat index equation. Heat index above 39 °C is dangerous — at 35 °C air temperature and 80% humidity, the heat index reaches 47 °C, approaching the limit of human thermoregulation.
Inputs
Temp F
Thermal state of the substance. Check whether the formula needs Celsius, Fahrenheit, or Kelvin (K = °C + 273.15).
Humidity Pct
Reference formula or conversion factor shown for context.
Results
heat index (°F)
A normalised score comparing the result to a reference baseline.
heat index (°C)
A normalised score comparing the result to a reference baseline.
danger category
The classification bucket this result falls into based on the computed value and the applicable reference scale.
actual temperature
The value at the specified point or condition.
humidity
Reference formula or conversion factor shown for context.
