About K to °F
Turn Kelvin readings from science texts into Fahrenheit for a US audience.
Temperature scales have different zero points, so you cannot just multiply: use °F = (K − 273.15) × 9/5 + 32. For example, 293.15 K = 68 °F.
Kelvin: the SI scale starting at absolute zero; a change of 1 K equals 1 °C. Fahrenheit: water freezes at 32 °F and boils at 212 °F at sea level.
