For an exact conversion between degrees Fahrenheit and Celsius, and kelvins of a specific temperature point, the following formulas can be applied. Here, f is the value in degrees Fahrenheit, c the value in degrees Celsius, and k the value in kelvins: f °F to c °C: c = f − 32 / 1.8 c °C to f °F: f = c × 1.8 + 32
A heat burst is claimed to have sent the air temperature to near 140 °F (60 °C), supposedly causing cotton crops to become desiccated and drying out vegetation. [24] While it is possible the reading may have exceeded 100 °F (38 °C), the thermometers designed to detect temperatures up to 140 °F (60 °C) broke. [25] 6 July 1966
Scalding injuries can occur within 15 seconds of exposure to water that is 133 degrees Fahrenheit, or 56 degrees Celsius. At 125 degrees Fahrenheit, or 52 degrees Celsius, scalding injuries may occur in 90 seconds. Scalds are more common in children, especially from the accidental spilling of hot liquids.
This definition served the following purposes: it fixed the magnitude of the kelvin as being precisely 1 part in 273.16 parts of the difference between absolute zero and the triple point of water; it established that one kelvin has precisely the same magnitude as one degree on the Celsius scale; and it established the difference between the ...
Unlike the degree Fahrenheit and degree Celsius, the kelvin is no longer referred to or written as a degree (but was before 1967 [1] [2] [3]). The kelvin is the primary unit of temperature measurement in the physical sciences, but is often used in conjunction with the degree Celsius, which has the same magnitude. Other scales of temperature:

To convert a delta temperature from degrees Fahrenheit to degrees Celsius, the formula is {ΔT} °F = 9 / 5 {ΔT} °C. To convert a delta temperature from degrees Celsius to kelvin, it is 1:1 ({ΔT} °C = {ΔT} K).
300 years ago scientist Daniel Fahrenheit invented a temperature measurement — donning his last name. Once Fahrenheit came up with the blueprint for the modern thermometer, using mercury — he ...
