2500 mL = 2500 / 1000 = 2,5 L
catatan: 1 L = 1000 mL, 1 mL = 1/1000 L
4 km = 4 x 100.000 = 400.000 cm (4 x 10⁵ cm)
catatan: 1 km = 1000 m = 100.000 cm
2 kg = 2 x 1.000.000 = 2.000.000 mg (2 x 10⁶ mg)
catatan: 1 kg = 1000 g = 1.000.000 mg
4 cm = 4 / 100.000 = 0,00004 km (4 x 10⁻⁵ km)
catatan: 1 km = 1000 m = 100.000 cm, 1 cm = 1/100.000 km
2 g = 2 / 1000 = 0,002 kg (2 x 10⁻³ kg)
catatan: 1 kg = 1000 g, 1 g = 1/1000 kg
360 km/jam = 360 x 1000/3600 = 100 m/s
catatan: 1 km = 1000 m, 1 jam = 3600
900 kg/m³ = 900 x 1000/1000.000 = 0,9 gr/cm³
catatan: 1 kg = 1000 g, 1 m³ = 100.000 cm³ -

A. 2500 ml = ....L
1 ml = [tex] \frac{1}{1000} [/tex] L
2500 ml = 2500 : 1000
= 2,5 L
B. 4 km =......... cm
1 km = 100.000 cm
4 km = 4 × 100.000 cm
= 400.000 cm
C. 2 kg = ....... mg
1 kg = 1.000.000 mg
2 kg = 2 × 1.000.000 mg
= 2.000.000 mg
D. 4 cm = ...... km
1 cm = 1/100.000 km
4 cm = 4 : 100.000 km
= 0,00004
E. 2 g =...... kg
1 g = 1/1000 kg
2 g = 2 : 1000
= 0,002 g
F. 360 km/jam = .... m/s
= 360 × 1000 per 1 × 3600
= 360.000 m per 3600 s
= 100 m/s
G. 900 kg/m³ = ........ g/cm³
= 900 × 1000 per 1 × 1.000.000
= 900.000 per 1.000.000
= 0,9 g/cm³
