How many centimeters are in one kilometer?
12x3x5.5x40x8 = 63,360
Originally, the meter was based on the polar circumference of the earth
with the measurement going through Paris. The meter was to be one
ten-millionth (1/10,000,000) of the distance from the equator to the North
100 x 1000 = 100,000
Pole. If the Academy's measurements were correct, the distance from
the equator to the North Pole would be ten
(Hint: Refer to Frame 4-11.)
(number of centimeters in a
meter times number of
meters in a kilometer)
NOTE: The polar circumference of the earth is estimated to be
40,000,008 meters. The distance from the equator to the North Pole is
1/4 the polar circumference, or about 10,000,002 meters.
NOTE: The earth is not a perfect sphere. The circumference of the earth
measured around the equator is around 40,075,160 meters.
UNITS OF DISTANCE. In the metric system, the most commonly used
measurements of distance are the meter, kilometer, centimeter, and
Since one millimeter equals 0.001 meter and one centimeter equals 0.01
meters, how many millimeters are in one centimeter?
