Common Temperature Conversions: Room, Body, Weather, Cooking, and Baking
The temperatures you actually need to convert in daily life — room temperature, body temperature, oven settings, weather ranges, freezer and fridge. This guide converts each one in both directions with context.
The conversions people look up most are room temperature, body temperature, and a moderate oven. Convert between the two scales with
°C = (°F − 32) × 5/9going one way and°F = °C × 9/5 + 32going the other. This guide extends that to every temperature you meet in daily life, in both directions.
For any value not on these charts, use our Celsius to Fahrenheit converter or Fahrenheit to Celsius converter.
What room temperature converts to
The comfortable indoor range is what thermostats default to. Cooler settings suit an office, warmer settings start to call for a fan. Convert any value yourself with the Fahrenheit to Celsius calculator or the Celsius to Fahrenheit calculator.
Storage labels mean something narrower. When a lab report says store at room temperature it usually points to a defined band, and pharmaceutical controlled room temperature is tighter still.
What body temperature converts to
Clinical thresholds are set in Celsius worldwide, while consumer thermometers in the US read in Fahrenheit. The everyday rule that a reading just above normal is not really a fever lines up with the upper-end-of-normal row below.
What weather temperatures convert to
Outdoor readings span from arctic cold to dangerous heat. Run sub-zero values through the Fahrenheit to Celsius calculator to see the worked steps.
What oven and cooking temperatures convert to
Cooking is where the gap between the two scales matters most, because reading a US oven setting as if it were Celsius would ruin dinner. Convert any baking temperature with the Celsius to Fahrenheit calculator.
Fan ovens run hotter than they read. UK recipes often list two settings because a convection oven cooks faster than its dial suggests, so a fan figure matches a higher conventional one.
Fan runs hotter by = 15–20°C
Fan 160°C ≈ conventional 180°CGas ovens use their own scale. UK gas marks map onto both Celsius and Fahrenheit on a fixed ladder.
What fridge and freezer settings convert to
Food safety guidance is given as a ceiling for the fridge and a target for the freezer. The USDA keeps the fridge at or below its safe limit and the freezer at the recommended deep-cold setting.
What extreme temperatures convert to
Industrial and natural heat reaches far past anything a kitchen sees. Convert extreme values with the Fahrenheit to Celsius calculator.
How the formulas work
Both directions come down to one exact formula each, plus a rough mental shortcut when you only need a ballpark.
F → C : subtract 30, divide by 2 C → F : double, add 30

Common questions
Room temperature is the comfortable indoor band that thermostats default to, expressed in Celsius for the standard cool-to-warm range. Lab and pharmaceutical labels define a slightly different storage window.
Normal body temperature converts to a single round Celsius figure, which is why clinical thresholds worldwide are stated on that scale. A fever officially begins at the next clinical mark.
A moderate oven, the standard for most baking, converts to a familiar Celsius setting. Apply °C = (°F − 32) × 5/9 to any other oven figure.
A fan or convection oven cooks faster than its dial reads, so lower the conventional setting before you bake. Drop the figure to match the convection difference.
Convection runs hotter by = 15–20°C
Conventional 180°C → fan 160°CFood safety guidance gives a maximum for the fridge and a target for the freezer, both available in either scale.
