10 μm is equal to which of the following?
100 nm
0.01 mm
1 cm
10,000 mm
The correct answer and explanation is:
The correct answer is 0.01 mm.
To explain:
1 micrometer (μm) is equal to 1/1,000 of a millimeter (mm), or 0.001 mm. So when we convert 10 μm, it’s equal to 10 times 0.001 mm, which gives us 0.01 mm.
Here’s a breakdown of the other options:
- 100 nm:
Nanometers (nm) are smaller than micrometers. 1 μm is equal to 1,000 nm. So 10 μm would be 10,000 nm, not 100 nm. - 1 cm:
1 centimeter (cm) is equal to 10 millimeters, or 10,000 micrometers. So 10 μm is much smaller than 1 cm. - 10,000 mm:
This would be 10 meters, or 10,000 millimeters, much larger than 10 μm. This option is not correct.
Thus, 10 μm is equivalent to 0.01 mm because 1 μm = 0.001 mm, and multiplying 10 μm by 0.001 gives 0.01 mm. This is a common conversion used in scientific fields, such as biology and materials science, where measurements at the microscopic level are important.
