  2. Fahrenheit - Wikipedia

    en.wikipedia.org/wiki/Fahrenheit

    A temperature interval of 1 °F was equal to an interval of 5 ⁄ 9 degrees Celsius. With the Fahrenheit and Celsius scales now both defined by the kelvin, this relationship was preserved, a temperature interval of 1 °F being equal to an interval of 5 ⁄ 9 K and of 5 ⁄ 9 °C. The Fahrenheit and Celsius scales intersect numerically at −40 ...

  3. Conversion of scales of temperature - Wikipedia

    en.wikipedia.org/wiki/Conversion_of_scales_of...

    Converting units of temperature differences (also referred to as temperature deltas) is not the same as converting absolute temperature values, and different formulae must be used. 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 ...

  4. Degree (temperature) - Wikipedia

    en.wikipedia.org/wiki/Degree_(temperature)

    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.

  5. Celsius - Wikipedia

    5 ⁠x + 32) °F. The degree Celsius is the unit of temperature on the Celsius temperature scale[ 1] (originally known as the centigrade scale outside Sweden), [ 2] one of two temperature scales used in the International System of Units (SI), the other being the closely related Kelvin scale. The degree Celsius (symbol: °C) can refer to a ...

  6. Temperature - Wikipedia

    en.wikipedia.org/wiki/Temperature

    In this scale, a temperature difference of 1 degree Celsius is the same as a 1 kelvin increment, but the scale is offset by the temperature at which ice melts (273.15 K).

  9. Absolute zero - Wikipedia

    en.wikipedia.org/wiki/Absolute_zero

    The theoretical temperature is determined by extrapolating the ideal gas law; by international agreement, absolute zero is taken as −273.15 degrees on the Celsius scale (International System of Units), [1] [2] which equals −459.67 degrees on the Fahrenheit scale (United States customary units or imperial units).
