Final answer:
To convert micrometers to millimeters, divide the number of micrometers (50 µm) by 1,000, resulting in 0.05 mm.
Step-by-step explanation:
To convert micrometers to millimeters, we need to understand the metric prefixes and their respective multiplication factors. One millimeter (mm) equals 1,000 micrometers (µm), since the prefix 'milli-' represents 10-3 or 1/1,000, and 'micro-' represents 10-6 or 1/1,000,000.
So, to convert 50 micrometers to millimeters, we divide the number of micrometers by 1,000:
50 µm / 1,000 = 0.05 mm
Therefore, 50 micrometers is equal to 0.05 millimeters.
