Answer:
87 Fahrenheit = 30.56 Celsius
Celsius = (Fahrenheit - 32) x 5/9
= (87-32) x 5/9
= 30.56 degrees Celsius
87 F = 30.56 C
roughly speaking it's betwee to 30 and 31 C A quick formula for converting from C to F is double the Temp in C and remove 10% from that then add 32 the reverse will give you the temp in C 87-32 = 55 55/.9 =61.11 61.11 / 2 = 30.5555555
