Multiple Choice

Which SI base unit is used to measure length?

• moles (mol)

• meters (m)

• grams (g)

• liters (L)

Multiple Choice

Which SI base unit is used to measure volume?

• moles (mol)

• meters (m)

• grams (g)

• liters (L)

Multiple Choice

Which SI base unit is used to measure mass?

• moles (mol)

• meters (m)

• grams (g)

• liters (L)

Multiple Select

Which two SI units are used to measure temperature? (select all that apply)

• Celcius (°C)

• Kelvin (K)

Match

Match the following prefixes with the correct units:

• kilograms

• millimeters

• centiliters

• hectograms

• decimeters

kg

mm

cL

hg

dm

• kg

• mm

• cL

• hg

• dm

Converting between prefixes...

Remember the acronym:
King Henry Dead By Drinking Chocolate Milk

As you move left and right between the prefixes, your decimal will also move left and right in the number. Going from big prefixes to small prefixes will make the number BIGGER!

EXAMPLE: 1.0 kilograms (kg) = ?? milligrams (mg)
(decimal moving to the right... add zeros as you need to!)
1.0 kg --> 1000000.0 mg (six zeros added behind the one)

Converting between prefixes...

Remember the acronym:

King Henry Dead By Drinking Chocolate Milk

As you move left and right between the prefixes, your decimal will also move left and right in the number. Going from small prefixes to big prefixes will make the number SMALLER!

EXAMPLE: 1.0 milligrams (mg) = ?? kilograms (kg)
(decimal moving to the left... add zeros as you need to!)
1.0 mg --> 0.000001 kg (five zeros added in front of the one)

Reorder

Reorder the following from largest (1st) to smallest (5th):

• Kilo

• Deka

• deci

• centi

• milli

1

2

3

4

5

• 1
• 2
• 3
• 4
• 5

EX: 10 is considered 10.0
6 would be 6.0
150 would be 150.0
4201 would be 4201.0
*just add point zero to the end

If you get a whole number with no decimal, the decimal falls at the end of the number.
