Question

us standard metric
0 f -17.7778 c

the measured temperature
in the us, temperature in non-scientific fields is expressed in degrees fahrenheit (°f).
for scientific purposes and in the rest of the world, temperature is expressed in kelvin (k) and
degrees celsius (or centigrade (°c)).
to convert:
f = c x 9/5 + 32
c = (f - 32) x 5/9

convert degrees fahrenheit (°f) to degrees celsius (°c) two consecutive times.

85 °f equals how many °c?
29.44 °c
thats right.

30 °f equals how many °c?
°c
check

Explanation:

Step1: Identify the formula for conversion

The formula to convert Fahrenheit (F) to Celsius (C) is \( C=(F - 32)\times\frac{5}{9} \). Here, \( F = 30 \).

Step2: Substitute the value of F into the formula

First, calculate \( F - 32 \): \( 30-32=-2 \).
Then, multiply the result by \( \frac{5}{9} \): \( -2\times\frac{5}{9}=-\frac{10}{9}\approx - 1.11 \).

Answer:

\( -\frac{10}{9}\approx - 1.11 \)
