Metric Conversion Mastery

The video tutorial explains two-step metric conversions, where a number with one prefixed unit is converted to another prefixed unit. The example problem involves converting 23.7 hectograms to milligrams. The process is broken down into two main steps: first, converting hectograms to grams, and then grams to milligrams. The tutorial emphasizes the importance of setting up fractions correctly and ensuring the desired unit appears in the final position before performing calculations. The final answer is calculated using multiplication and division of the conversion factors.

What is a two-step metric conversion?

• A conversion involving non-metric units
