To convert Fahrenheit to Celsius, you can use the formula: C = (F – 32) × 5/9. In this case, you would plug in -10 for F.
So, the calculation looks like this:
C = (-10 – 32) × 5/9
This simplifies to:
C = (-42) × 5/9
When you do the multiplication, you get:
C = -210/9, which equals approximately -23.33.
Therefore, minus 10 degrees Fahrenheit is about -23.33 degrees Celsius.
