How do you convert Celsius to Fahrenheit's?

Answer 1

Here are some different methods submitted by the community:

To convert Celsius to Fahrenheit, use this basic formula. C = 5/9 (F-32)

Temperature Celsius = 5/9 (Temperature Fahrenheit - 32)

The reverse formula is F = 9/5 C +32

Temperature Fahrenheit = (9/5 x Temperature Celsius) + 32

______

Use this equation to convert degrees Celsius/Centigrade (ºC) to degrees Fahrenheit (ºF): [°F] = [°C] × 1.8 + 32

________

F to C: Deduct 32, then multiply by 5, then divide by 9

C to F: Multiply by 9, then divide by 5, then add 32

________

Here's a simpler way that I've used for many, many years. Let's use an example of 16C. Double it to 32 and subtract the first digit (3), leaving 29. Now add the 29 to 32F (freezing point) and the answer in Fahrenheit is 61F.

Again, if the temperature is 24F - double to 48 - less the 4 = 44. Add that to 32. The result is 76F. This method works in negative values as well. -9C - double to 18, minus the 1=17. 32F minus 17 = 15F. Much simpler math than multiplying by 9 followed by division - and it's always spot on accurate.

Answer 2

Start by taking the number in Fahrenheit and subtracting 32. Then divide the number by 9, and then multiply it by 5. This is how you convert Fahrenheit to Celsius or use the equation C = (F - 32) × 5/9

Answer 3

Use this basic formula:

F = 9/5 C + 32

Temperature Fahrenheit = (9/5 x Temperature Celsius) + 32

The reverse formula is C = 5/9 (F - 32)

Temperature Celsius = 5/9 (Temperature Fahrenheit - 32)

Another formula:

°C = (°F - 32)/1.8

°F = (1.8 x °C) + 32

Another method:

F to C: Deduct 32, then multiply by 5, then divide by 9

C to F: Multiply by 9, then divide by 5, then add 32
Use this equation to convert degrees Fahrenheit (ºF) to degrees Celsius/Centigrade (ºC): [°C] = ([°F] - 32) × 0.556

°Celsius (or °Centigrade) to °Fahrenheit: [°F] = [°C] × 1.8 + 32

Answer 4

Subtract 32 from it, then multiply the result by 0.55 .

Answer 5

You multiply by 9/5, then you add 32. In other words:

F = (9/5)C + 32

Answer 6

Multiply C by 9/5 and then add 32 - so 100 C /5 = 20 x 9 = 180 + 32 = 212

100 C = 212 F

Answer 7

Given a temperature of x degrees Celsius, its equivalent is

= 5/9*(x-32) deg F

Answer 8

F = 9C/5 + 32

or 1.8C + 32

This may look more difficult, but in fact, an easy way to multiply by1.8 is to multiply by 2 and then take away a tenth of the answer.

Answer 9

F (Fahrenheit) = 32 + 1.8 xC (Celsius)
