Question

How do you convert 50°F to Celsius?

Answer 1

`50^@F = color(green)(10^@C)`

Explanation:

#{: (,"Fahrenheit","Celsius"), ("boiling point",212^@F,100^@C), ("freezing point",32^@F,0^@C), ("difference", 180F^@,100C^@) :}#

So
`color(white)("XXX")180 F^@=100C^@`

`color(white)("XXX")1F^@=100/180C^@`

`50^@F`
`color(white)("XXX")` is `50^@F-32^@F`
`color(white)("XXXX")=18F^@` above freezing.

`18F^@ = 18xx100/180C^@=10C^@`

`10C^@` above freezing is `10^@C`
