This tool will calculate the difference in temperature between two measured temperatures T 1 and T 2 and will convert any combination of temperature units for each temperature value. Absolute zero is defined as -459.67℉.Ī temperature difference of 1℉ is the equivalent of a temperature difference 0.556℃.īased upon the definitions of the Centigrade scale and the experimental evidence that absolute zero is -273. Temperature scale converter Temperature difference converter User Guide. Therefore, a degree on the Fahrenheit scale is 1/180 of the interval between the freezing point and the boiling point of water. This puts the boiling and freezing points of water exactly 180 degrees apart. This can be seen because the temperature interval between 20℃ and 30℃ is the same as between 30℃ and 40℃, but 40℃ does not have twice the air heat energy of 20℃.Ī temperature difference of 1 deg C is the equivalent of a temperature difference 1.8☏.įahrenheit is a thermodynamic temperature scale, where the freezing point of water is 32 degrees Fahrenheit (℉) and the boiling point 212℉ (at standard atmospheric pressure). The temperature T in Kelvin (K) is equal to the temperature T in degrees Celsius (☌) plus 273.15. The Celsius scale is an interval system but not a ratio system, meaning it follows a relative scale but not an absolute scale. Free online temperature converter - converts between 6 units of temperature, including kelvin K, Celsius ☌, Fahrenheit ☏, Rankine °R, etc. 0 degrees Celsius is equal to 273.15 degrees Kelvin: 0 ☌ 273.15 K. This means that 100℃, previously defined as the boiling point of water, is now defined as the equivalent to 373.15K. Use our Temperature Conversion calculator to quickly convert between units of temperature include Celsius, Fahrenheit, Newton, Kelvin, Delisle, and more. Zero on the Celsius scale (0℃) is now defined as the equivalent to 273.15K, with a temperature difference of 1 deg C equivalent to a difference of 1K, meaning the unit size in each scale is the same. ![]() Advertisement Although initially defined by the freezing point of water (and later the melting point of ice), the Celsius scale is now officially a derived scale, defined in relation to the Kelvin temperature scale.
