It depends on whether you are measuring the thickness of the board (5 mm) or length (5 dm).
cm, meters, dm, km, mm for canada
10 cm = 1 decimetre so 5 cm = 0.5 decimetres.
Try using a bit of common sense, shall we? 5 mm is less than half the width of a finger. 5 cm is about the length of a finger 5 dm is about the length of your forearm (and hand) 5 m is about three times as long as you are tall. Now see if you can work out which is the most appropriate.
1 dm = 10 cmSo 5 cm = 0.5 dm
5 ft = 15.24 dm
1 dm = 1 cm → 1 dm² = 1 dm × 1 dm = 10 cm × 10 cm = 100 cm² → To convert dm² to cm² multiply by 100 → 5 dm² = 5 × 100 cm² = 500 cm².
It is 3 to 5 because 5 dm = 50 cm
Yes, 550 m is greater than 5 dm because, one dm corresponds to 10 m and if there are 5 dm, it is equal to 50 m and obviously, 550 m is greater than 5 dm.
1dm = 10cm Therefore, 5 cm = 1/10 x 5 dm = 0.50 dm.
5 dm is 0,5 m a half meter :D
500 mm = 5 dm
