Step-by-step explanation:
1). ∵ 1 L = 1000 ml
  ∴ 4 L = 4000 ml
2). ∵ 1 cm = 10 mm
  ∴ 5 cm = 50 mm
3). ∵ 1 mg = 0.1 cg
  ∴ 5 mg = 0.5 cg
4). ∵ 1 ml = 0.001 L
  ∴ 25 ml = 0.025 L
5). ∵ 1 gm = 1000 mg
  ∴ 0.125 gm = 25 mg
6). ∵ 1 ml = 0.001 L
  ∴ 570 ml = 0.57 L
7). ∵ 1 mm = 0.1 cm
  ∴ 135 mm = 13.5 cm
8). ∵ 1 mg = 0.001 g
  ∴ 1820 mg = 1.82 g
9). ∵ 1 g = 100 cg
  ∴ 0.5 g = 50 cg
10). ∵ 1 ml = 0.001 L
   ∴ 0.2385 ml = 0.0002385 L
