nm. A nanometer represents 10 ^ -9 or one billionth of a meter.
And if you want inch: Here is. 1 inch = 2.54 cm; 15 cm divided by 2.54 = 5.90 inches
10 mm x 6.0 m = 10 mm x 6(1,000 mm) = 10 mm x 6,000 mm = (10 x 6,000) (mm x mm) = 60,000 mm^2
Circumference of a circle = π × diameter = π × 80 mm = 80π mm ≈ 251 mm
8000 mm !

It's better to stick with the ETRTO marking of diameter (in mm) and width (in mm). A 700C tire will be 622 x 23-38 mm. 23 mm width for a road bike, 38 mm for a hybrid.
for instance 205/55/20 205 is 205 mm across the tire (width) 55 is 55 mm the profile 55 is a low profile tire (height of wall) And 20 is diameter or the rim ( size of the rim)
