About Temperature Measurement
Temperature is a measure of thermal energy and heat intensity. Our converter handles the three primary temperature scales: Celsius (metric), Fahrenheit (imperial), and Kelvin (scientific absolute scale) with precise conversion formulas.
Temperature Conversion Formulas
Celsius to Fahrenheit: °F = (°C × 9/5) + 32Fahrenheit to Celsius: °C = (°F - 32) × 5/9Celsius to Kelvin: K = °C + 273.15Kelvin to Celsius: °C = K - 273.15
