How many centimeters in 78 kilometers?

Answer 1

Prefix 'centi' is used to denote sub multiples of meter and uses factor 0.01.

Prefix 'kilo' is used to denote multiples of meter and uses factor 1000.

Therefore to convert kilometers to centimeters, first kilometers are converted to meters and then meters to centimeters.

1. To convert kilometers to meters, value in kilometers has to be multiplied by factor used with prefix 'kilo':

78 kilometers = [kilometers] * 1000 = 78 * 1000 = 78000 meters

2. To convert meters to centimeters, value in meters has to be divided by factor used with prefix 'centi':

78000 meters = [meters] / 0.01 = 78000 / 0.01 = 7800000 centimeters

78 kilometers = 7800000 centimeters
