(The degree, in Celsius and measured relative to a base temperature, is identical to the kelvin, the SI base unit). Expressed as a proper SI unit, a quantity of kelvin second is four orders of magnitude higher than the corresponding degree day (1 Celsius degree-day is 8.64×10 4 K·s; 1 Fahrenheit degree-day is 4.8×10 4 K·s).
Joseph-Nicolas Delisle. The Delisle scale is a temperature scale invented in 1732 by the French astronomer Joseph-Nicolas Delisle (1688–1768). [1] The Delisle scale is notable as one of the few temperature scales that are inverted from the amount of thermal energy they measure; unlike most other temperature scales, higher measurements in degrees Delisle are colder, while lower measurements ...
* Normal human body temperature is 36.8 °C ±0.7 °C, or 98.2 °F ±1.3 °F. The commonly given value 98.6 °F is simply the exact conversion of the nineteenth-century German standard of 37 °C. Since it does not list an acceptable range, it could therefore be said to have excess (invalid) precision.
A minute of arc, arcminute (arcmin), arc minute, or minute arc, denoted by the symbol ′, is a unit of angular measurement equal to 1 / 60 of one degree. [1] Since one degree is 1 / 360 of a turn, or complete rotation, one arcminute is 1 / 21 600 of a turn.
A shortcut method for degrees Celsius is to count the number of chirps in 8 seconds (N 8) and add 5 (this is fairly accurate between 5 and 30 °C): T C = 5 + N 8 {\displaystyle \,T_{C}=5+N_{8}} The above formulae are expressed in terms of integers to make them easier to remember—they are not intended to be exact.
Most scientists measure temperature using the Celsius scale and thermodynamic temperature using the Kelvin scale, which is the Celsius scale offset so that its null point is 0 K = −273.15 °C, or absolute zero. Many engineering fields in the US, notably high-tech and US federal specifications (civil and military), also use the Kelvin and ...
One microfortnight is equal to 1.2096 seconds. [2] This has become a joke in computer science because in the VMS operating system, the TIMEPROMPTWAIT variable, which holds the time the system will wait for an operator to set the correct date and time at boot if it realizes that the current value is invalid, is set in microfortnights.
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
