A temperatura ye una magnitut fisica que representa lo clamato calor y frío. Se puede describir como a transferencia d'a enerchía termica entre os diferents cuerpos. Dende o punto de vista microscopico ye a enerchía cinetica de un cuerpo, o movimiento d'as particlas

A temperatura se mide con un termometro.

Ta medir as temperaturas bi ha muitas escalas:

• Grau Celsius: Se define esliyendo os 0 °C en o punto de fusión de l'augua y os 100 °C en o suyo punto d'ebullición.
• Kelvin: A escala de temperatura termodinamica (absoluta) a on que o zero absoluto, a teorica ausencia d'enerchía.
• Grau Fahrenheit: Se divide entre o punto de conchelación de una disolución de cloruro amonico (a valor que le se asigna ye zero) y a temperatura normal corporal humana (a valor que le se asigna ye 100). Ye una unidat que se fa servir en os Estaus Unius.
• Grau Réaumur: S'emplega ya procesos industrials, como d'almíbar.
• Grau Rømer: Hue no se fa servir.
• Grau Newton: Hue no se fa servir.
• Escala Leiden: Emplegato ta baixas temperaturas. Hue no se fa servir.
• Escala Delisle: Hue no se fa servir.

As siguientes formulas asocian as diferents escalas de temperatura:
