କ'ଣ Heat Index Calculator?

▾

The heat index (feels-like temperature) combines air temperature and relative humidity to determine the apparent temperature. High humidity impairs the body's ability to cool itself through sweating, making hot conditions feel significantly hotter than the thermometer reads.

କିପରି Heat Index Calculator

▾
  1. 1Uses the Rothfusz regression equation (NWS, USA)
  2. 2Only applicable when temperature > 27°C (80°F) and humidity > 40%
  3. 3Below this threshold, the actual temperature is used directly
  4. 4HI = −42.379 + 2.04901523T + 10.14333127RH − 0.22475541TH − 0.00683783T² − 0.05481717RH² + ...

ବିଶେଷ ଟିପ

During heat advisories, stay hydrated (drink before you feel thirsty), avoid outdoor activity during peak hours (10 AM–4 PM), and check on elderly neighbours who are most vulnerable.

ଆପଣ ଜାଣନ୍ତି କି?

The human body can only cool effectively when sweat evaporates. At 35°C with 100% humidity, sweat cannot evaporate at all — the body's cooling system effectively shuts down.
