Question

part a: the metric system
uses of metric measurement:
sports: track and field day races are 100m, 200m and 400 m.
food: a can of pop is 355 ml.
the mass of a bag of sugar is 1 kg.
travel: the speed limit in ontario is posted in km/h.
metric conversions
use this chart to help you convert from one unit to another.

distance	capacity	mass
1 cm = 10 mm	1 l = 1000 ml	1 g = 1000 mg
1m = 1000 mm	1kl = 1000 l	1 kg = 1000 g
1 m = 100 cm		1 kg = 1 000 000 mg
1 km = 1000 m

if you are converting in the order of the chart, multiply. ex: cm to mm, x 10
if you are converting in the opposite direction, divide ex. mm to cm, ÷ 10
examples
0.36 l = __________ ml 1200 m = __________ km
0.36 x 1000 ml in 1 l 1200 ÷ 1000 m in 1 km
so... 0.36 l = 360 ml so... 1200 m = 1.2 km
practice
convert each measurement to the unit specified.
6 cm = __________ mm 4 g = __________ mg
500 m = __________ km 1500 ml = __________ l
1.2 kg = __________ mg 234 mm = __________ m
400 l = __________ ml 0.5 kg = __________ g

Explanation:

Step1: Convert 6 cm to mm

Since 1 cm = 10 mm, multiply 6 by 10. So, $6\times10 = 60$ mm.

Step2: Convert 4 g to mg

As 1 g = 1000 mg, multiply 4 by 1000. So, $4\times1000=4000$ mg.

Step3: Convert 500 m to km

Given 1 km = 1000 m, divide 500 by 1000. So, $500\div1000 = 0.5$ km.

Step4: Convert 1500 mL to L

Since 1 L = 1000 mL, divide 1500 by 1000. So, $1500\div1000 = 1.5$ L.

Step5: Convert 1.2 kg to mg

As 1 kg = 1000000 mg, multiply 1.2 by 1000000. So, $1.2\times1000000 = 1200000$ mg.

Step6: Convert 234 mm to m

Given 1 m = 1000 mm, divide 234 by 1000. So, $234\div1000=0.234$ m.

Step7: Convert 400 L to mL

Since 1 L = 1000 mL, multiply 400 by 1000. So, $400\times1000 = 400000$ mL.

Step8: Convert 0.5 kg to g

As 1 kg = 1000 g, multiply 0.5 by 1000. So, $0.5\times1000 = 500$ g.

Answer:

6 cm = 60 mm
4 g = 4000 mg
500 m = 0.5 km
1500 mL = 1.5 L
1.2 kg = 1200000 mg
234 mm = 0.234 m
400 L = 400000 mL
0.5 kg = 500 g
