how to convert between metric units:

1. identify starting and ending unit.
2. count the number of \jumps\ to get from the starting to ending unit. decide the direction you are moving.
3. move the decimal the same number of \jumps\ in the same direction. add zeros as needed.

example #1
3.0 km = _ meters
example #2
645 mg = _ grams
example #3
350 cm = _ meters

Explanation:

Step1: Recall metric - length unit

The metric unit for length is the meter.

Step2: Recall metric - capacity unit

The metric unit for capacity is the liter.

Step3: Recall metric - weight unit

The metric unit for weight is the gram.

Step4: Solve Example #1

Identify starting unit (km) and ending unit (m). There are 3 "jumps" from km to m moving right. Since 1 km = 1000 m, for 3.0 km, we multiply by 1000. So, 3.0×1000 = 3000 m.

Step5: Solve Example #2

Identify starting unit (mg) and ending unit (g). There are 3 "jumps" from mg to g moving left. Since 1 g=1000 mg, for 645 mg, we divide by 1000. So, 645÷1000 = 0.645 g.

Step6: Solve Example #3

Identify starting unit (cm) and ending unit (m). There are 2 "jumps" from cm to m moving left. Since 1 m = 100 cm, for 350 cm, we divide by 100. So, 350÷100 = 3.5 m.

Answer:

The metric unit for length is meter.
The metric unit for capacity is liter.
The metric unit for weight is gram.
Example #1: 3000
Example #2: 0.645
Example #3: 3.5
