there are 200 cm in 20 dm
20 inches = 50.8 cm (20 in.)(2.54 cm/in.) = 50.8 cm 1 inch = 2.54 cm Algebraic Steps / Dimensional Analysis Formula20 in*2.54 cm 1 in=50.8 cm 20 inches is 50.8 centimeters.
20 sq cm = 20*100 sq mm = 2000 sq mm
As 1 feet= 30.48 cms So 20 feet= 30.48 * 20 =609.6 cm
1 dm = 10 cm so 20 dm = 20*10 = 200 cm. Simple!1 dm = 10 cm so 20 dm = 20*10 = 200 cm. Simple!1 dm = 10 cm so 20 dm = 20*10 = 200 cm. Simple!1 dm = 10 cm so 20 dm = 20*10 = 200 cm. Simple!
20 ft = 609.6 cm
1 cm = 1/100 meters 20 cm = 20/100 =0.2 meters
200mm
200mm
10 cm = 1 dm 20 cm = 2 dm
10 mm = 1cm 20 mm = 2 cm
20 and a half cm.
20 millimeters is 2cm
Area of the circle: pi*20*20 = 400*pi square cm

By unit of length and distance and conversion ,we can say that 1 km=100000 cm 20 cm =0.0002 km
20 sq cm = 20*100 sq mm = 2000 sq mm
