Metric System Prefixes (Unit 1)

Question 1

Base SI unit

Answer 1

distance = meters (m) volume = Liters (L) mass = grams (g)

Question 2

kilo- (k)

Answer 2

1000 base units 1 km = 1000 m 1 kL = 1000 L 1 kg = 1000 g

Question 3

hecto- (h)

Answer 3

100 base units 1 hm = 100 m 1 hL = 100 L 1 hg = 100 g

Question 4

deka- (da or D)

Answer 4

10 base units 1 dam = 10 m 1 daL = 10 L 1 dag = 10 g

Question 5

deci- (d)

Answer 5

0.1 base units 1 m = 10 dm or 1 dm = 0.1 m 1 L = 10 dL or 1 dL = 0.1 L 1 g = 10 dg or 1 dg = 0.1 g

Question 6

centi- (c)

Answer 6

0.01 base units 1 m = 100 cm or 1 cm = 0.01 m 1 L = 100 cL or 1 cL = 0.01 L 1 g = 100 cg or 1 cg = 0.01 g

Question 7

milli- (m)

Answer 7

0.001 base units 1 m = 1000 mm or 1 mm = 0.001 m 1 L = 1000 mL or 1 mL = 0.001 L 1 g = 1000 mg or 1 mg = 0.001 g

Question 8

Micro- (µ)

Answer 8

10^-6 base units

1 m = 10⁶ µm or 1 µm = 10^-6 m

1 L = 10⁶ µL or 1 µL = 10^-6 L

1 g = 10⁶ µg or 1 µg = 10^-6 g

Question 9

nano- (n)

Answer 9

10^-9 base units

1 m = 10^{<span>9</span>} nm or 1 nm = 10^-9 m

1 L = 10^{<span>9</span>} nL or 1 nL = 10^-9 L

1 g = 10⁹ ng or 1 ng = 10^-9 g
