-40°F is how many °C?
\({40 \over 9}\) |
|
-40 |
|
\(-{40 \over 9}\) |
|
-8 |
The formula to convert from F° to C° is:
\(C° = {5 \over 9} (F° - 32)\)
plugging in our values gives:
\(C° = {5 \over 9} (-40 - 32)\)
\(C° = {5 \over 9} (-72) = {{-72 \times 5} \over 9}\)
\(C° = {-360 \over 9}\)
\(C° = -40\)
When the clouds become too saturated with water, the water is released as precipitation in the form of:
