1 cm = 0.001km
1 km = 10,000cm
cm to m = divide by 100 m to km = divide by 1000so cm to km = divide by 100 000.
8 cm in km would be 0.00008km
6.954321 km = 695432.1 cm Just move the decimal over 5 places to change from 1000 m/km to 0.01 m/cm
multiply by 100 000 21.1 km = 2110000.00 cm
0.5km = 50,000 cm (km x 100,000 = cm)
1 mile = 1.609344 km The formula to convert miles to km 1 mi * 63360 in 1 mi * 2.54 cm 1 in * 1 km 100000 cm = 1.609344 km
cm
1 cm = 0.000001 km so 4 cm = 0.000004 km
To convert centimetres to kilometres, you would divide the number by 100,000. So, for example, 1,000,000 centimetres is equal to 10 kilometres. Similarly, 7 centimetres is equal to 0.00007 kilometres.
If you are talking about metric measurements, 1 cm does not equal 5 km. There are 100,000 cms in a km, so 5 km is actually 500,000 cm To answer your question going along with your assumption that if 1cm = 5 km, there would be 8.5 km in 1.7cm (1.7 x 5 = 8.5)
Km
A kilometer (km) is much larger than a centimeter (cm). There are 100,000 cm in one km.
