1000 · 1 kilogram equals 1000 grams.
True · Multiply litres by 1000 to get millilitres: 2.5 × 1000 = 2500.
1000 · 1 litre equals 1000 millilitres.
Hill A · 2.34 km is 2340 m, which beats Hill B's 1800 m.
1.8 litres is more · 1.8 litres is 1800 ml, which beats 1,750 ml.
True · 3.75 litres is 3750 ml, and 3750 is more than 3705.
1400 · 0.35 x 4 = 1.4 kg, and 1.4 kg is 1400 g.
2500 g · 1.25 x 2 = 2.5 kg, which is 2500 g.
10 · 4 x 250 = 1000 cm, which is 10 m.
6 · 1500 m ÷ 5 min = 300 m per minute. In 20 minutes that is 6000 m, which is 6 km.
