Metric Stair ChartMetric Stair Chart

When you move When you move downdown the stairs you are the stairs you are multiplying by 10 for each step. multiplying by 10 for each step. Example:Example:

• 100 grams to milligrams, you are moving downwards on the 100 grams to milligrams, you are moving downwards on the stairs.stairs.

• Pretend you are standing on the gram stair and to get to the Pretend you are standing on the gram stair and to get to the milli-milli-gram stair, you move down 3 steps multiplying by 10 gram stair, you move down 3 steps multiplying by 10 each time. each time.

• 100 x 10 = 1,000         1,000 x 10 = 10,000     10,000 x 10 = 100 x 10 = 1,000         1,000 x 10 = 10,000     10,000 x 10 = 100,000 100,000

or or 100 x 1000 = 100,000100 x 1000 = 100,000    or you can use the shortcut and just move the decimal place or you can use the shortcut and just move the decimal place

100 grams = 100,000 milligrams.100 grams = 100,000 milligrams.

For every step upward on the chart you are For every step upward on the chart you are dividing by 10 or moving the decimal one place dividing by 10 or moving the decimal one place to the left.. to the left.. Example:  Example: 

To convert 1000 milligrams to grams you are moving To convert 1000 milligrams to grams you are moving upward on the stairs:  upward on the stairs: 

• Pretend you are standing on the milli-gram stair and to get to Pretend you are standing on the milli-gram stair and to get to the 1-gram stair, you move up 3 steps dividing by 10 each the 1-gram stair, you move up 3 steps dividing by 10 each time. time.

• 1000/10 = 100         100/10 = 10     10/10 = 1 1000/10 = 100         100/10 = 10     10/10 = 1 or or 1000/1000 = 11000/1000 = 1
