A kilometre (km) is a decimal multiple of the meter, the International System of Units (SI) unit of length. To calculate a value in meters to the corresponding value in kilometres, just multiply the quantity in meters by 0.001.
1000 meters make 1 kilometre
hence, 1 meter makes 1/1000 kilometre
and 100 meters make 1/1000 × 100 = 100/1000 = 110 kilometres.
