How many micrometers are in a cell that measures 1.45mm?

• A. 145 um
• B. 1450 um
• C. 14.5 um
• D. 0.145 um

Answer: (B)

To convert millimeters to micrometers, it's essential to understand the relationship between the two units of measurement. One millimeter (mm) is equal to 1,000 micrometers (μm). Therefore, to convert 1.45 mm to micrometers, you can multiply by 1,000. 1.45 mm x 1,000 μm/mm = 1,450 μm. This calculation shows that the cell measuring 1.45 mm is equivalent to 1,450 micrometers. Thus, the correct answer is that the cell measures 1,450 micrometers. Understanding this conversion is crucial for accurate measurements in biology, where different scales are frequently used to describe cell sizes and structures.
