1 mile =1.609 km.=1609m=1609000mm
Hence, 1 mm = (1/1609000) mile
Therefore, 400 mm = (400/1609000) mile = .00025mile (approx.)
1125
the answer to that is 4cm
400mm equals 15.74 inches. Direct Conversion Formula400 mm* 1 in 25.4 mm = 15.7480315 in
.4 meters=400 mm
0.4m2
400 millimeters is 0.4 meters.
4 dm is greater than 400mm
4
400 mm = 1.31 feet, approx.
400mm = 0.4m 90cm = 0.9m 0.5m = 0.5m 0.9m > 0.5m > 0.4m, so 90cm is the longest.
600mm * 400mm = 0.6m * 0.4m = 0.24 sq metres
Well a mm is half a cm so i think they are the same equivalent.
