text: There are 3 main temperature scales.\n\nThe earliest, Fahrenheit, was invented in 1724 by Daniel Gabriel Fahrenheit, a German Physicist. This scale is still used widely in America.\n\nThe next and most "metric" of the scales, Celsius, was invented in 1742 by Sweedish astronomer Anders Celsius. This scale is the standard in Europe.\n\nThe last scale, Kelvin, is the SI standard measurement for temperature. It was invented in 1848 by Lord William Thomas Kelvin. The kelvin scale starts at absolute zero, therefore 0 C/32 F is equivalent to 273.15K
