The length of a blackboard can vary depending on the specific blackboard in question. Standard sizes for blackboards typically range from 1.2 meters to 3 meters in length. This would be equivalent to 120 cm to 300 cm or 0.0012 km to 0.003 km. It is important to measure the specific blackboard to determine its exact length in meters, kilometers, or centimeters.

What is the length of a blackboard 10 m or 10 cm?

It could be either one. I'd have to see the blackboard. If it's 10m, it's in a very large room. If it's 10cm, it's a very tiny blackboard.

How many km in a cg?

You have km (kilometers) which is length, and cg (centigrams) which is mass. These two units cannot be converted between each other. Assuming maybe you meant cm (centimeters) instead of cg, then: 1 km = 1000 m & 1 cm = 0.01 m, so 1 cm * [.01 (m/cm)] / [1000 (m/km)] = 0.00001 km = 10-5 km

Which is bigger 41.7km or 100700cm?

41.7 km, here's how:Get them into a common unit (try meters).1 m = 100 cm, so (100700 cm) * (0.01 m/cm) = 1007 m.1 km = 1000 m, so (41.7 km) * (1000 m/km) = 41700 m,So 41.7 km is larger.Additional info:To get the conversion factor, look at the equation [1m = 100 cm], then divide both sides by (100 cm) --> 0.01 m/cm = 1 ;So length/length is an non-dimensional factor. Multiplying by 1, does not change the value; you can also divide both sides by 1m --> 1 = 100 cm/m, which you would need to divide by 1: 100700 cm / 1 is the same as (100700 cm) / (100 cm/m) = 1007 m

What is the largest cm mm or km?

The conversion between km, m and cm are given .On finding the relation we get as follows . we know, 1 km=1000 m=100000 cm. from the above we can conclude , km > m > cm.
