3,000,000
There are 10^3 mm in 1 metre, and 10^3metres in a km. Therefore there are10^6 mm in a km.
There are 30 millimetres in 3cm
It would be 3 cm.
There are 10 millimetres in one centimetre. Therefore, 9 centimetres 3 millimetres is equal to 9 x 10 + 3 = 93 millimetres.
There are 100 millimetres in one decimetre. Therefore, 3 decimetres is equal to 3 x 100 = 300 millimetres.
There are 10000 millimetres in one decametre. Therefore, 3 decametres is equal to 3 x 10000 = 30000 millimetres.
There are 3,000,000 millimetres in 3 kilometres. 10 mm = 1 cm 100 cm = 1 m 1000 m = 1 km
There are 10 millimetres in one centimetre. Therefore, 3 centimetres is equal to 3 x 10 = 30 millimetres.
Answer: 3 mi. = 4.82803 km
There are 32 millimetres in 3 centimetres 2 millimetres.
There are 304.8 millimetres in one foot. Therefore, 3 feet is equal to 304.8 x 3 = 914.4 millimetres.
One kilometre is equal to 1000 x 1000 = 1000000 millimetres. Therefore, 3 millimetres is equal to 3/1000000 = 0.000003 kilometres.
