Heat Index (Feels Like)

Calculate risk of heat disorders based on NOAA regression. Essential for summer safety.

Wind Chill

Determine how cold it feels with wind. Includes NWS frostbite warnings.

Dew Point

Find the temperature where condensation begins. A true measure of humidity comfort.

Wet Bulb Temp

Estimate wet bulb temperature from standard air temp and humidity using the Stull method.

WBGT Index

Wet Bulb Globe Temperature estimation for athletic and industrial heat stress monitoring.

Boiling Point

Calculate water boiling temperature at any altitude using atmospheric pressure physics.

Understanding Temperature Metrics

Temperature affects everything from human health to industrial processes. While a standard thermometer tells you the "dry air" temperature, it rarely tells the whole story.

Our suite of calculators helps you uncover the hidden variables:

  • Safety: Use the Heat Index and WBGT tools to prevent heat stroke in workers and athletes.
  • Comfort: The Dew Point connector reveals why 30°C in a rainforest feels worse than 35°C in a desert.
  • Engineering: Solve thermal expansion and capacity problems for material science usage.

General FAQ

Heat Index measures how hot it feels in the shade based on humidity. WBGT (Wet Bulb Globe Temperature) is more comprehensive, accounting for direct sunlight (radiation) and wind speed, making it the standard for outdoor athletic safety.
The NWS Wind Chill model is specifically designed for cold stress. Above 50°F (10°C), wind chill effect on the human body is considered negligible regarding frostbite or hypothermia risk, so the formula is undefined.
These tools use standard regression formulas (NOAA, NWS, BOM, Stull) widely accepted for general estimation. For critical safety or laboratory precision, direct measurement with calibrated instruments is always recommended.
