The Millimeter (mm) is perfect for very small measurements like the thickness of a credit card (0.76 mm), the diameter of a pencil lead (0.5-0.7 mm), or the size of small hardware components. Commonly used in engineering, jewelry design and manufacturing. Micrometers (µm) measure cells (human cell = ~10–30 µm), bacteria (1–5 µm), and microelectronics. Pollen grains are ~15–100 µm wide.
To convert between Millimeter (mm) and Micrometer (µm), use the following formulas:
1 Millimeter (mm) = 1000.0000000000001 Micrometer (µm)
1 Micrometer (µm) = 0.001 Millimeter (mm)
1 mm = 1 * 1000.0000000000001 µm = 1000.0000000000001 µm
8 mm = 8 * 1000.0000000000001 µm = 8000.000000000001 µm
30 mm = 30 * 1000.0000000000001 µm = 30000.000000000004 µm
90 mm = 90 * 1000.0000000000001 µm = 90000.00000000001 µm
120 mm = 120 * 1000.0000000000001 µm = 120000.00000000001 µm
245 mm = 245 * 1000.0000000000001 µm = 245000.00000000003 µm
559 mm = 559 * 1000.0000000000001 µm = 559000.0000000001 µm
