What is 76 degrees Celsius equal to in Fahrenheit?

Answer 1

168.8F. Tip for cheating on future math homework: typing "76C in F" in Google gives you the answer and you don't even have to press enter. Most teachers require you to show your work, though.

F = 1.8*C + 32. 1.8*76 + 32 = 168.8° F

If you cannot remember the formula, just remember 32° F is 0° C, and 212° F is 100° C. You have two points. Then you can derive the equation of the line connecting the two points, and find any point on the line.

It's simple Algebra. If you know Celsius and want to find Fahrenheit, then let the x be Celsius and y be Fahrenheit.

So your two points are (0,32) and (100,212). Slope is rise/run = (y2 - y1) / (x2 - x1). m = (212 - 32) / (100 - 0) = 180/100 = 9/5 = 1.8

Then y - y1 = m(x - x1) --> y - 32 = 1.8*(x - 0) --> y = 1.8*x + 32, just like I had above. You could also use x2 and y2: y - 212 = 1.8*(x - 100) --> y = 1.8*x - 180 + 212 = 1.8*x + 32.

You can swap x and y if you know Fahrenheit and want Celsius, then the formula is C = (5/9)*(F - 32)
