The Kelvin-Celsius Bridge
273.15 K equals exactly 0 °C. This value represents the defined offset between the two scales — it is exact by definition, not a measured quantity. The triple point of water (273.16 K = 0.01 °C) was historically used to calibrate thermometers under the ITS-90 standard, and it differs from the freezing point by only 0.01 K due to the slight pressure dependence of the ice-water equilibrium.
Data Accuracy
Results on this page are produced by subtracting the exact offset of 273.15 from the Kelvin input, in accordance with the thermodynamic definition adopted by the SI. Internal arithmetic uses IEEE 754 double-precision, and displayed values are rounded to one decimal place. All figures are consistent with the ITS-90 temperature scale.
