![]() ![]() James Schombert, Department of Physics, University of Oregon – Temperature Scale (Glossary) – An overview of the 3 common temperature scales of today, Celsius, Fahrenheit, and Kelvin. NIST Physical Measurement Laboratory – SI Units – Temperature – Details on temperature by the National Institute of Standards and Technology. ![]() ISO 80000-5:2019 – The ISO standard defining temperature.Wikipedia – Celsius, Fahrenheit, Conversion of Units of Temperature, and Scale of Temperature – An introduction to both temperature scales and the concept of a temperature scale.Rankine (°R) increases at the same rate as the Fahrenheit scale, but is offset by 459.67° from Fahrenheit. Kelvin (°K) increases at the same rate as the Celsius scale, but is offset by 273.15° from Celsius. They are benchmarked off absolute 0 (the coldest temperature possible). Kelvin and Rankine are the two other temperature scales. What are other common temperature scales? Who uses Celsius and Fahrenheit?Ĭelsius is a “standard unit” and is commonly used worldwide.įahrenheit is used in the United States as well as some regions of the Pacific and the Caribbean. Today, Fahrenheit is benchmarked from the freezing point of water (32☏) and the boiling point of water (212☏). 50F 10C 60F 15.56C 70F 21.11C 80F 26.67C 90F 32.22C 98,6F 37C - average body temperature 100F 37.78C 212F 100C - boiling point of water Celsius The degree Celsius (symbol: C) is a unit of temperature on the Celsius scale. 100☏ was about the body temperature of a person. What is the difference between Celsius and Fahrenheit?Ĭelsius and Fahrenheit are two temperature scales.Ĭelsius is benchmarked from the freezing point of water (0☌) and the boiling point of water (100☌).įahrenheit’s origins are not certain, however it is believed that 0☏ was the freezing point of equal parts ice, water, and salt. Step 1: Subtract 32 from the temperature in Fahrenheit: 70 – 32 = 38.Step 2: Multiply that number by 5: 28 x 5 = 140.Step 1: Subtract 32 from the temperature in Fahrenheit The formula to convert F to C is: T(C) ( T(F) - 32) × 5/9 which is T(C) ( T(F) - 32) / 1.8 F to C Example Problem For example, convert 68 degrees Fahrenheit into degrees Celsius: T(C) (68F - 32) × 5/9 T (C) 20 C It's also easy to do the conversion the other way, from C to F.Formula – How to convert Fahrenheit (☏) to Celsius (☌) Formula 1: Easy to remember Temperature conversions are performed by using a formula, which differs depending on the two temperature scales you are converting between. ![]()
