There are 1,000,000 (one million) mm in a km.
Well you see, there are 100 metres in a kilometre.
There are 100 centimetres in a metre.
There are 10 millimetres in a centimetre.
So, 100 times 100 times 10 equals how many mm in a km.
That is 1,000,000 mm in a km!
1 km = 1×10^6 mm 1 kilometer = 1,000,000 millimeters
1 kilometer is 1 million millimeters.
1 km equals 100,000 mm
1000 mm = 1 metre = 10-3 km
1m = 1/1000 km 0.03 m = 0.03/1000 =0.00003 km
There are 10^3 mm in 1 metre, and 10^3metres in a km. Therefore there are10^6 mm in a km.
1000 mm = 1 m 1000 m = 1 km ⇒ 1000 x 1000 mm = 1000000 mm = 1 km ⇒ 50 mm = 50 ÷ 1000000 km = 0.00005 km
1 mm= 1/1000 km
1,000,000 mm = 1 km
1 km equals 100,000 mm
1000 mm = 1 metre = 10-3 km
1 million mm in 1 km.
1000 mm = 1 m = 0.001 km
There are 1000mm in a metre and 1000m in a kilometre so there would be 1000000 (1 million) millimetres in a kilometre.
To convert from mm to km, divide by a million. (1 km = 1000 m; 1 mm = 0.001 m.)
1 million mm per kilometer.
There are .00001 mm in 1 km.
5 mi is about 8.045 km. Since 1 km = 1 million mm, then 8.045 km = 8,045,000 mm. 5 mi = 8,045,000 mm.
The conversion between km and mm are given .On finding the relation we get as follows . 1 km =1000000 mm. 6 km =6000000 mm. ratio is equal to 6000000 :3000 mm. hence,2000:1 .
