Celsius

Definición

Una escala de temperatura métrica donde 0 °C es el punto de congelación del agua y 100 °C es el punto de ebullición a presión atmosférica estándar (101,325 kPa).

Explicación

Named after Swedish astronomer Anders Celsius, who proposed the scale in 1742. Convert to Fahrenheit: °F = (°C × 9/5) + 32; to Kelvin: K = °C + 273.15. Key reference points: −40°C equals −40°F (the only temperature where both scales agree); body temperature is 37°C (98.6°F); a comfortable room is 20–22°C (68–72°F). Celsius is the official temperature unit in 195 of 197 countries.
