Its a convenient length on a human scale.
distance
If you mean kilometres, the answer is distance.
Length is used to measure distance or height. It is measured in km , m ,cm.
The standard measure for distance is the METRE
Distance is measured in linear units like kilometers, while temperature is measured in degrees Celsius. Therefore, 10 km does not equate to a temperature in degrees Celsius.
The orbital distance of the Moon (which is measured from the *center* of the Earth) varies. The average is 384,400 km or 238,900 miles, and can be about 21,000 km (5%) different.
1 ligt year equals 5,878,625,373,184 miles or 9,460,730,472,581 km
The straight line distance would be 350 kilometers (3.5 x 100 km). Multiply the measured distance by the scale.
The distance from Bismarck, ND to Canada is about 150 miles (241 km) as measured on Google Maps.
By unit of length and distance and conversion ,we can say that the length of a finger is measured in cm.
Distance in physics refers to the amount of space between two points, measured along a straight line. It is a scalar quantity, meaning it has magnitude but no direction. Distance is commonly measured in meters (m) or kilometers (km).
There is no relation between speed and time. if you add up the distance than the speed or time can be measured according to the distance measured. for example we say car A traveled 5 km in 20 minutes with a speed of 15 km/hour
