In cooking, 160 degrees Celsius is equivalent to which gas mark?
Celsius value was 0.01023 °C with an uncertainty of 70 µK". This practice is permissible because the magnitude of the degree Celsius is equal to that of the kelvin. Notwithstanding the official endorsement provided by decision #3 of Resolution 3 of the 13th CGPM, which stated "a temperature interval may also be expressed in degrees Celsius", the practice of simultaneously using both °C and K remains widespread throughout the scientific world as the use of SI-prefixed forms of the degree Celsius (such as "µ°C" or "microdegrees Celsius") to express a temperature interval has not been well-adopted. One effect of defining the
Gas Mark (13.9 °C) each time the gas mark increases by 1. Below Gas Mark 1 the scale markings halve at each step, each representing a decrease of 25 °F. To convert gas mark to degrees Celsius (formula_1), multiply the gas mark number (formula_2) by 14, then add 121: formula_3 For the reverse conversion: formula_4 However it is usual to round the result of this calculation to a round number of degrees Celsius. Note that tables of temperature equivalents for kitchen use usually offer Celsius values rounded to the nearest 10 degrees, with steps of either 10 or 20 degrees between Gas
