Chapter 5, Heat and Temperature 5-3 Table 5-1. Celsius Temperature Conversion Formulae From Celsius To Celsius Fahrenheit [°F] = ([°C] × 9/5) + 32 [°C] = ([°F] – 32) × 5/9 Kelvin [K] = [°C] + 273.15 [°C] = [K] – 273.15 For temperature intervals rather than specific temperatures: ±1 °C = ±1 K = ±1.8 °F Table 5-2. Fahrenheit Temperature Conversion Formulae From Fahrenheit To Fahrenheit Celsius [°C] = ([°F] – 32) × 5/9 [°F] = ([°C] × 9/5) + 32 Kelvin [K] = ([°F] + 459.67) × 5/9 [°F] = ([K] × 9/5) – 459.67 For temperature intervals rather than specific temperatures: ±1 °F = ±.56 °C = ±.56 K A thermometer changes readings due to the addition or subtraction of heat. Heat and temperature are not the same, but they are related. Figure 5-1 gives a comparison of Kelvin, Celsius, and Fahrenheit temperature scales. Figure 5-1.
