Feels Like & Safety Calculator
This tool estimates the "feels like" temperature and potential weather-related health risks. It automatically calculates either the Heat Index for warm conditions or the Wind Chill for cold conditions.
How to Use:Enter the air temperature. The calculator will automatically show the relevant field (Humidity for heat, Wind Speed for cold). Then, select your activity level to get a risk assessment and safety tips.
Heat Index (Hot Weather): Valid for temps ≥ 80°F (27°C) and humidity ≥ 40%. [1]
Wind Chill (Cold Weather): Valid for temps ≤ 50°F (10°C) and wind speeds ≥ 3 mph (5 km/h). [2]
Temperature Conversion Formulas:°C = (°F - 32) * 5/9 °F = (°C * 9/5) + 32
