Since the length of a nautical mile, for practical purposes, is equivalent to about a minute of latitude, a distance in nautical miles on a chart can easily be measured by using dividers and the latitude scales on the sides of the chart. Recent British Admiralty charts have a latitude scale down the middle to make this even easier. [10]
The US Open Tennis Championships, commonly called the US Open, is a hardcourt tennis tournament organized by the United States Tennis Association annually in Queens, New York City. It is chronologically the fourth and final of the four Grand Slam tennis events, held after the Australian Open , French Open , and Wimbledon .
A bonus pool of $1,000,000 is also to US Open champions who have clinched the first place of the US Open Series. [ 14 ] In the U.S. National Championships, Richard Sears (1881–1887), William Larned (1901–1902, 1907–1911) and Bill Tilden (1920–1925, 1929) hold the record for most titles in the men's singles, with seven victories each.
Reversing this yields the formula for obtaining a quantity in units of Celsius from units of Fahrenheit; one could have started with the equivalence between 100 °C and 212 °F, which yields the same formula. Hence, to convert the numerical quantity value of a temperature T[F] in degrees Fahrenheit to a numerical quantity value T[C] in degrees ...

Some 2000s era Buicks have a single speed gauge with a button on the instrument panel to switch the scale between MPH and km/h. Other vehicles have digital speedometers which can be set to read out speeds in either MPH or km/h. Another common unit of speed is meters per second (m/s), used especially for lifts and cable cars.
Speed is the magnitude of velocity (a vector), which indicates additionally the direction of motion. Speed has the dimensions of distance divided by time. The SI unit of speed is the metre per second (m/s), but the most common unit of speed in everyday usage is the kilometre per hour (km/h) or, in the US and the UK, miles per hour (mph).
The distance travelled by the ball in feet is the 'speed' of the putting green. Six distances, three in each of two opposite directions, should be averaged on a flat section of the putting green. The three balls in each direction must be within 8 inches (20 cm) of each other for USGA validation of the test. [7]
