How the value is converted
1 mm × 1,000 = 1,000 µm
Feet and inches use the international definition (1 ft = 0.3048 m).
The first answer is rounded to two decimal places for results of 1 or more, or three significant digits below 1; the exact figure keeps 10 significant digits. Why rounding early changes the answer.
