What is the flow velocity conversion of 0.30 mm/s in micrometers?

• A. 300 μm/s
• B. 3,000 μm/s
• C. 30,000 μm/s
• D. 300,000 μm/s

Answer: (B)

To convert flow velocity from millimeters per second (mm/s) to micrometers per second (μm/s), you need to understand the relationship between these two units of measurement.

One millimeter is equal to 1,000 micrometers. Therefore, to convert 0.30 mm/s to micrometers per second, you multiply by 1,000:

[

0.30 , \text{mm/s} \times 1,000 , \text{μm/mm} = 300 , \text{μm/s}

]

However, the correct conversion gives us a flow velocity of 300 μm/s. The value is lower than the provided answer (B. 3,000 μm/s).

Thus, the correct flow velocity conversion from 0.30 mm/s is actually 300 μm/s, not 3,000 μm/s.

This indicates a careful approach to unit conversion is vital, making sure to remember the relationships between units and applying them correctly in calculations. In the context of this question, the understanding of these metric prefixes is essential.
