1 mm = 1/1000 m = 0,001 m
4 hm = 4* 100 m = 400m
1 dag = 1/100 kg = 0,01 kg
4 mg = 4/1000.000 kg = 0,000004 kg
10 kuintal = 10*10 kg = 100kg

6 jam + 30 s = 6*3600 + 30 = 21600+ 30 s= 21630 s

10 hari + 5jam + 0,15
= 86400*10 + 50*3600 + 9s
= 864.000+ 180.000 + 9 s
= 1044009 s

14 jam = 14*3600 s = 50.400 s

1 hari + 2jam+ 45 menit
= 86.400 s + 7200 s + 2700 s
= 96300 s

6 menit = 6 * 60 s = 360 s
