How many micrometers are there in one meter?

One meter is equivalent to one million micrometers because the metric system operates on powers of ten. Specifically, 1 meter equals 1,000 millimeters, and each millimeter is equal to 1,000 micrometers. Therefore, to convert meters to micrometers, you would multiply as follows:

1 meter = 1,000 millimeters

1 millimeter = 1,000 micrometers

Combining these conversions gives:

1 meter = 1,000 mm * 1,000 μm/mm = 1,000,000 micrometers.

In exponential notation, 1,000,000 is represented as (10^6). Thus, there are (10^6) micrometers in one meter, affirming why this answer is the correct one.
