Establishing the upper and lower bounds of normal using standard deviation. up vote 1 down vote favorite. I understand the concept of standard deviations and z-values, but I'm trying to figure out if standard deviations alone are good for establishing the upper and lower bounds for normal.
There are 1.0E-6 kilometer in a millimeter. 1 Millimeter is equal to 1.0E-6 Kilometer. 1 mm = 1.0E-6 km. Millimeter is one the most commonly used units of length which equals to 1/1000th of a meter. It is a unit of SI applicable for measuring small distances and small length.
It doesn't matter what unit of distance is used, as long as it is the same in both cases. On a 1:250 000 scale map, 1 centimeter on the map represents 250 000 centimeters (exactly 2.5 kilometers) on the ground. On the same map, one inch on the map represents 250 000 inches (about 3.9457 miles) on the ground.
