There are 111.85 miles per hour in 185 kilometers per hour. Each kilometer per hour is equal to .6213 miles per hour.
People who travel a kilometer per hour are traveling a slightly shorter distance than people who travel a mile per hour because a kilometer is shorter than a mile. Kilometers per hour are a measurement of a slightly faster speed than miles per hour because there are more kilometers required to take up the same distance than miles. Kilometers are a common form of measurement in countries that utilize the metric system as their main means for measuring distances. Countries that utilize the metric system will often have road signs that dictate the speed drivers should be traveling in kilometers per hour.
Miles are commonly used in the United States and any other countries that choose to use the United States' domestic measurement system. Road signs in the United States are equipped with miles per hour speed limit signs that tell drivers how fast they are allowed to go. Most cars are equipped with both kilometer per hour and mile per hour readings on the instrument panel. If the country that the car was purchased in is one that follows the domestic system, the kilometers per hour will be slightly smaller underneath the miles per hour gauge.
