What is the value represented by the prefix "hecto"?

The prefix "hecto" denotes a factor of 100, which is equivalent to 10 raised to the power of 2 (10^2). This means that when you see the prefix "hecto" in measurements, it indicates that the unit being described is multiplied by 100. For example, one hectometer is equal to 100 meters.

Understanding metric prefixes is essential in calibration and measurement, as it allows for clear and consistent communication of values in various scientific and technical fields. The other choices represent different metric prefixes: "kilo" corresponds to 10^3 (or 1,000), "mega" corresponds to 10^6 (or 1,000,000), and "giga" corresponds to 10^9 (or 1,000,000,000), and none of these are applicable to "hecto."
