How to Calculate Weather
What is Weather?
Weather calculators include heat index, wind chill, dew point, UV index interpretation, and unit conversions for temperature, pressure, and precipitation.
Step-by-Step Guide
- 1Wind chill: 13.12 + 0.6215T − 11.37V^0.16 + 0.3965T×V^0.16 (°C, km/h)
- 2Heat index: complex equation with temperature and relative humidity
- 3Dew point ≈ T − (100 − RH)/5 (simple approximation)
- 4UV index: < 2 low risk; 3–5 moderate; 6–7 high; 8+ very high
