Celsius to Fahrenheit Converter

F = C x 9 / 5 + 32. The 9/5 changes the step size, because 100 Celsius degrees cover the same span as 180 Fahrenheit degrees between freezing and boiling. The 32 shifts the starting point, because water freezes at 0 C and 32 F.

What is 22 C in Fahrenheit?

71.6 F. That is 22 x 9/5, which is 39.6, plus 32. It is where most thermostats outside the US sit, and it matches the 72 F that most American ones are set to.

How do I convert Celsius to Fahrenheit in my head?

Double it and add 30. For 22 C that gives 74 against a true 71.6. The shortcut runs a few degrees high in warm weather and is very close in cold weather, which is the half of the year you need it for.

What Celsius temperature is a fever?

38 C, which is 100.4 F, is the usual threshold. Normal body temperature is 37 C or 98.6 F, and 40 C is 104 F, which is the point at which most guidance says to seek help.

What are the common oven temperatures in Fahrenheit?

160 C is 320 F, 180 C is 356 F, 190 C is 374 F and 200 C is 392 F. Recipes round these to 325, 350, 375 and 400, because an oven dial cannot hold the difference anyway.

Why do the two scales meet at -40?

Because they run at different rates from different starting points, and -40 is the one temperature where the two disagreements cancel out exactly. It is the only number that is the same in both scales, which makes it the easiest conversion on this page.
