To find out how many kilometers 0.5 cm represents on the map, you can set up a proportion. Since 2 cm represents 50 km, you can write the proportion as 2 cm is to 50 km as 0.5 cm is to x km. Cross multiplying, you get 2 * x = 0.5 * 50. Solving for x, you find that 0.5 cm on the map represents 12.5 kilometers.
2 km = 2*105 cm
0.00002 km is 2cm
200,000 cm
1 cm = 10-2 metres =10-5 km So, 8.5 cm = 8.5*10-5 km = 0.000085 km
2 km = 200 000 cm To convert from km to cm, multiply by 100 000.
1 km = 1000 metres and 1 metre = 100 cm so 28 km = 28000 m = 2 800 000 cm
2 cm = 150 km 4 cm = 300 km
You will see a distance of 5 cm on your map represent a 2 km distance across the landscape. Your 2 km is 2,000 meters, and there are 100 cm in a meter. That makes for 200,000 cm in 2 km. If you "reduce" or scale it down by a factor of 40,000, you'll get 200,000 / 40,000 = 5 cm.
By unit of length and distance and conversion ,we can say that 1 km =100000 cm 2 km =200000 cm
20 km is 2 million cm
2 km
