14 kg =

1. 14 g
2. 1.400 g
3. 140 g
4. 14.000 g

k is for kilo = 1000

14 (kg) x 1000 = 14000 g

14 kg = 14000 g

0.435 kg

1. 435 g
2. 0.000435 g
3. 1435 g
4. 04.35 g

k is for kilo = 1000

0.435 (kg) x 1000 = 435 g

0.435 kg = 435 g

760 g =

1. 0.760 kg
2. 0.000760 kg
3. 760 kg
4. 7600 kg

k is for kilo = 1000

760 g / 1000 = 0.760 kg

760 g= 0.760 kg

370 mg =

1. 370 g
2. 0.000370 g
3. 370,000 g
4. 0,370 g

m is for milli = 0.001

370 (mg) x 0.001 = 0.370 g

370 mg= 0.370 g

0.0048 g =

1. 0.0048 mg
2. 4.8 mg
3. 0.048 mg
4. 0.0000048 mg

m is for milli = 0.001

0.0048 (g) / 0.001 = 4.8 mg

0.0048 g= 4.8 mg

0.7 dm3 =

1. 7000 cm3
2. 70 cm3
3. 700 cm3
4. 7 cm3

1 dm³ = 1000 cm³

0.7 (dm³⁾ x 1000 = 700 cm³

0.7 dm³= 700 cm³

42 cm3 =

1. 42000 dm3
2. 42 dm3
3. 0,042 dm3
4. 0,42 dm3

1 cm³ = 0.001 dm³

42 (cm³⁾ x 0.001 = 0.042 dm³

42 cm³= 0.042 dm³

4.5 dm3 =

1. 45000 L
2. 45 L
3. 0.0045 L
4. 4.5 L

1 dm³ = 1 Liter

4.5 (dm³⁾ x 1 = 4.5 L

4.5 dm³= 4.5 L

0.675 m3 =

1. 675,000 mL
2. 675 mL
3. 0.675 mL
4. 0.000675 mL

1 m³ = 1,000 Liter

1 m³ = 1,000,000 mLiter

0.675 (m³⁾ x 1,000,000 = 675,000 mL

0.675 (m³= 675,000 mL

94 mL =

1. 940 cm3
2. 94 cm3
3. 0.094 cm3
4. 94000 cm3

1 m³ = 1,000 Liter

1 dm³  (/1000) = 1 Liter

1 cm³  (/1000) = 1 mLiter (/1000)

94 cm³               = 94 mL  

The figure shows a conical flask

which has been drawn three

times and a scale has been

indicated on each of them.

The lines of the scale are

graduated in 50 mL steps.

Explain on which conical flask

the scale has been indicated

correctly.

Which flask has the correct scale?

1. A
2. B
3. C
4. None

The narrower the flask

becomes, the larger the

height difference will

need to become to

achieve the same volume

increase, so flask B

 

A swimming pool is 25 m long,
12 m wide and 3 m deep.
Calculate how many m3 of water the swimming pool contains.

1. 300 m3
2. 900 m3
3. 900,000 m3
4. 300 L

V= l _* w _* h

V= 25 _* 12 _* 3

V = 900 m³

calculate how many liters of water
the swimming pool contains

1. 9 L
2. 90 L
3. 900 L
4. 900,000 L

1 m³ = 1000 L

900m³ = 900 _* 1000L

V = 900,000 L

Tony has a solid chess piece.

First he determines the mass

of the chess piece: 16,2g.

Then he submerges the chess

piece in a water-filled

measuring jug.
