Environmental Formulas
Key environmental science formulas for weather, air quality, and climate calculations.
Air Quality Index (AQI) Formula
Convert pollutant concentrations to AQI values. Understand air quality levels from good to hazardous.
Carbon Footprint Formula
Estimate CO2 emissions from energy use, travel, and consumption. Calculate your environmental impact in tonnes of CO2.
Heat Index Formula
Calculate the apparent temperature from air temperature and humidity. Understand how hot it really feels outside.
Stream Discharge Formula
Calculate the volume of water flowing in a river or stream per unit time. Used in hydrology and water management.
Wind Chill Formula
Calculate how cold it feels when wind is factored in. Used by weather services to warn about frostbite risk.
