40 mm = 4e-5 km
Full precision:0.00004 km
Feet + Inches:5' 2"
Step-by-Step Solution
To convert 40 millimeters to kilometers, we divide by 1000000 because one kilometer equals exactly 1000000 millimeters.
1 kilometer = 1000000 millimeters
Since there are 1000000 millimeters in every kilometer, we divide our value by this factor:
40 ÷ 1000000 = 4e-5 kilometers
So 40 millimeters = 4e-5 kilometers.
Quick check: 4e-5 × 1000000 = 40 millimeters
