Heat Conversion Calculator

The main temperature scales are: 1) Celsius (°C) - water freezes at 0°C, boils at 100°C, 2) Fahrenheit (°F) - water freezes at 32°F, boils at 212°F, 3) Kelvin (K) - absolute scale starting at -273.15°C, 4) Rankine (°R) - absolute scale starting at -459.67°F. Common conversions: °F = °C × 9/5 + 32, K = °C + 273.15.

Common heat energy conversions include: 1) 1 BTU = 1,055 Joules = 0.252 kilocalories, 2) 1 kilocalorie = 4,184 Joules = 3.966 BTU, 3) 1 kilowatt-hour = 3,412 BTU = 3,600,000 Joules, 4) For power: 1 BTU/hour = 0.293 watts. Always consider the context (heating/cooling systems, food energy, industrial processes).

Heat energy and temperature are related but distinct: 1) Temperature measures molecular kinetic energy, 2) Heat energy (Q) depends on mass, specific heat capacity, and temperature change (Q = mcΔT), 3) Same temperature change in different materials requires different heat energy, 4) Heat capacity determines energy needed per degree change, 5) Phase changes require additional latent heat energy.

Heat transfer rates depend on: 1) Temperature difference (larger difference = faster transfer), 2) Material properties (thermal conductivity, specific heat), 3) Surface area (larger area = faster transfer), 4) Heat transfer method (conduction, convection, radiation), 5) Medium properties (air vs. liquid cooling), 6) Flow rates in convection systems.
