Every 1 KM/H = 0.621371 MPH
(1°C × 9/5) + 32 = 33.8°F, (2°C × 9/5) + 32 = 35.6°F, (3°C × 9/5) + 32 = 37.4°F, (10°C × 9/5) + 32 = 50°F
For example on the 10 degrees C. 9/5 is also equal to 1.8. So, 10x1.8=18 Since freezing is 0 C and 32 F
to get what 10C is in F, we start at 32 add the 18 ( 10x1.8) and that = 50F.
20C will be 32+ 36(20x1.8) = 68 F
30C will be 32+ 54( 30x1.8) = 86F
40C will be 32+ 72 ( 40x1.8)= HOT otherwise known as 32+72=104F
50C = DAMN HOT=otherwise known as 32+90=122F
which I hear it can get in the Outback of OZ, Death Valley USA, or Middle East
