The document discusses converting between different units of measurement using conversion factors. It provides examples of converting between units of time, length, mass, and volume. The key steps for conversion are: 1) Write the number with original units, 2) Multiply by the conversion factor as a fraction, 3) Cancel out the original units, 4) Multiply the numbers on top and divide the numbers on bottom. Practice problems are provided to convert between units of volume like km3 to m3, cm3 to mm3, and dm3 to cm3.

1. Converting
Metric units

2. Conversion Factors
- are relationships between units
that we know to be true.

3. EXAMPLES:
1 Minute = ____seconds60
12 inches = ____foot1
1 day = ____hours24
16 ounces = ____lb1

4. Steps in converting units:
1. Write the number (with units) that you want
to convert.
2. Multiply itby conversion factor, writtenas a
fraction.
3. Make sure the old units cancel.
4. Multiply all the numbers on the top and
divide the numbers on the bottom.
