Hot oven

A hot oven is a kitchen appliance used for baking or roasting food at elevated temperatures.

200 °CTemperature
0 K · absolute zero
Celsius and Fahrenheit zero points are offsets. Compare temperature differences, not ratios in °C or °F. The kelvin axis starts at absolute zero.

A little perspective

150 degrees Celsius is 50 K lower than the temperature of a hot oven.

Measurements, assumptions & sources +

150 degrees Celsius

Temperature: 150 °C; definition.

Celsius and Fahrenheit have shifted zero points. Differences are useful; “twice as hot” in °C or °F is not a physical temperature ratio.

NIST — SI conversion factors

Hot oven

Temperature: 200 °C; defined reference.

A defined 200 °C oven setting; air and food temperatures are different.

Defined examples — our methodology

The marked temperature is calibrated. Unmeasured illustration details are representative.

Relative size
We compare temperatures using a difference in kelvins, not a ratio.

How to read the visual

The diagram uses the recorded measurements. Details outside the marked spans do not set the scale.

  • The temperature of a hot oven: This is an illustrative comparison value, not a claim that every example is the same.

Compare temperature differences in kelvins; Celsius and Fahrenheit ratios are not meaningful.
