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

• A conversion involving two prefixed units

• A conversion involving a single prefixed unit

• A conversion involving two different units without prefixes

What is the first step in a two-step metric conversion?

• Convert directly to the desired unit

• Divide the given value by 10

• Put the given value as a fraction over one

• Multiply the given value by 10

Why do we need to cancel out the initial unit in the first step?

• To avoid using a calculator

• To make the fraction easier to read

• To ensure the unit is converted correctly

• To simplify the calculation

What equivalent statement is used to convert hectograms to grams?

• 1 hectogram = 10,000 grams

• 1 hectogram = 100 grams

• 1 hectogram = 10 grams

• 1 hectogram = 1000 grams

What should you do if the desired unit hasn't appeared in the top last box?

• Divide by 10

• Multiply by 10

• Add another fraction

• Stop the conversion

Why is it important to not use the calculator until the desired unit appears in the top last box?

• To ensure the units are correctly canceled

• To make the process faster

• To avoid errors in the conversion

• To save time

What equivalent statement is used to convert grams to milligrams?

• 1 gram = 10 milligrams

• 1 gram = 100 milligrams

• 1 gram = 1000 milligrams

• 1 gram = 10,000 milligrams

What is the final step before using the calculator?

• Cross off all units

• Multiply all numbers

• Divide all numbers

• Add all fractions

How do you handle numbers in the final calculation?

• Divide all numbers by 10

• Add all numbers together

• Multiply numbers on the top and divide by numbers on the bottom

• Subtract numbers on the bottom from numbers on the top

What is the final answer for converting 23.7 hectograms to milligrams?

• 2.37 x 10^5 milligrams

• 2.37 x 10^6 milligrams

• 2.37 x 10^8 milligrams

• 2.37 x 10^7 milligrams
