One kilometre is equal to 1000 x 1000 = 1000000 millimetres. Therefore, 20 millimetres is equal to 20/1000000 = 0.00002 kilometres.
There are 1000 metres in a km and 1000 millimetres in a metre. Therefore, there are 1000000 millimetres in a kilometre. So 20*1000000 is 20,000,000 millimetres.
Millimetres and millimetres are the same measurement. Therefore, 20 millimetres is equal to 20 millimetres.
There are 10 millimetres in one centimetre. Therefore, 20 centimetres 57 millimetres is equal to (20 x 10) + 57 = 257 millimetres.
1km = 1000m = 100000cm = 1000000mm, or a million millimetres.
89,300,000 millimetres
25,000,000 millimetres
34,000 millimetres
There are one million millimetres in one kilometre. Therefore, 280 millimetres is equal to 280/1000000 = 0.00028 kilometres.
There are 10 millimetres in one centimetre. Therefore, 20 millimetres is equal to 20/10 = 2 centimetres.2 cm
There are 1000000 millimetres in one kilometre. Therefore, 2500 millimetres is equal to 2500/1000000 = 0.0025 kilometres.
There are 100000 millimetres in one kilometre. Therefore, 1.98 millimetres is equal to 1.98/100000 = 0.0000198 kilometres.
There are 304.8 millimetres in one foot. Therefore, 20 feet is equal to 20 x 304.8 = 6096 millimetres.
