Metric Units Notes

2 Conversion Chart

One dekameter = 10 meters 10 = dekameter One 10 = dekagram One liters 10 = dekaliter One

3 Conversion Chart

One decimeter = 1/10 meter 1/10 = decimeter One 1/10 = decigram One liter 1/10 = deciliter One 4

What does this mean?

When converting metric units of measurement, we use powers of 10.

6 Key ideas:

● Bigger Units to smaller Units: MULTIPLY

● Smaller Units to Bigger Units: DIVIDE

● **Use the Conversion Chart!!** 7 Conversion Chart:

Units of Length (Metric)

Definition: The distance between two points. ⊸ Centimeter (cm), Decimeters (dm), Meters (m), kilometers (km) 10

Units of Length

11 Examples:

Meters Centimeters ➔ To convert from meters to centimeters, you must 1 100 multiply by 100.

2 200 ➔ To convert from centimeters to meters, you 3 ? must divide by 100. 4 ?

Meters Kilometers

➔ To convert from meters to 1,000 1 kilometers, you must divide by 1,000. 3,000 3

➔ To convert from 5,000 ? kilometers to meters, you must multiply by 1,000. ? 7

12

To start with #1, take a look at the chart on the right. There’s 2 meters and you want to find how many centimeters there are.

You first have to multiply the amount of meters there are by 100 centimeters.

2 x 100 = 13

For the other two questions, you are using a different unit. Be careful when converting.

200

3 x _? = ______? x _? = ______

Liquid Volume (Capacity)

Liquid Volume Definition: The capacity of an object (how much liquid it can hold). ★ Liters (L), Kiloliters (kL), Hectoliters (hL), Dekaliters (daL), Deciliters (dL), Centiliters (cL), Milliliters (mL)

21

Units of Capacity/Liquid Volume 22 Examples:

Liters milliliters ➔ To convert from liters to Milliliters, you must 1 1,000 multiply by 1,000.

2 2.000 ➔ To convert from milliliters to liters, you must divide by 3 ? 1,000. ? 4,000

Liters Hectoliters

➔ To convert from Liters to 100 1 hectoliters, you must divide by 100. 300 3

➔ To convert from 500 ? hectoliters to liters, you must multiply by 100. ? 7

Definition: ⊸ , Minutes, Hours, Days, Weeks, Months

26

Units of Time

⊸ To convert from minutes to seconds, you must multiply by 60

⊸ To convert from seconds to minutes, you must divide by 60

⊸ To convert from days to weeks, you must multiply by 7.

⊸ To convert weeks to days, you divide by 7.

29

Mixed Measures In mixed measures, you MUST have the same before you can combine the measures.

For example: 1 meter + 1 dekameter = 1 meter + 10 meters = 11 meters

30

Example

2 hours 30 minutes = ______minutes To find the total amount of seconds, convert the hours into minutes. 2 x 60 = 120. Then add the amount of minutes to the total. 120 + 30 = 150. There are 150 minutes total. 31 Examples:
