Chronometer measures longitude East or West of the prime meridian, 0 degrees, located on the longitudinal meridian running through Greenwich, England. A chronometer is simply a precise clock or watch capable of denoting time in the 24 hour basis. The time at Greenwich and all along the 0 prime meridian is known as GMT, Greenwich Mean Time or sometimes as "Zulo" time. The line at 180 degrees East or West is known as the International Date Line.

Lines of Latitude encircle the Earth horizontally, and are parallel to the Equator. Lines of Latitude are intercepted by Lines of Longitude. Lines of Longitude run vertically from the North Pole to the South Pole. The Prime Meridian is zero longitude and passes through the Greenwich Observatory, Greenwich, London, England.
Till now, there haven't been any such instrument developed which could predict the happening of earthquakes. So, their accurate prediction isn't possible till now.

For latitude the sextant, and later for longitude, the marine chronometer.
You continue to make it repeatedly, with measurements of several kinds if possible, and you enlist the help of several others to make the same observation repeatedly and with measurements.
Accuracy
Accurate measurements of time become possible after accurate measurement of length and mass because time taken by a heavy body to move a certain distance is more,and time taken by a light body to move a certain distance is less.
It seems reasonable to assume it does, but it has not been possible to get a large enough sample (or have measurements accurate enough) to confirm how it reacts to gravity.
There is a point on the Tropic of Capricorn at every possible longitude.
The answer will depend on the precision of the measurement. The fact that the answer is given to 2 decimal places does not imply that the measurement is accurate to 2 dp. It could have been measured using an instrument accurate to 0.02 units.
Latitude and longitude are expressed in terms of angle measure.They are measurements, referring to the angle of any point on earth, [east or west] of the Prime Meridian,and [north or south] of the equator.They're not divided into anything.The lines you see on a map or globe are not the only ones that exist, only a few shown for convenience.Similarly, the lines on a ruler or measuring tape are obviously not the only possible measurements.

No information about Meghan McCain's measurements is available. Since her measurements have nothing to do with her political positions, it is quite possible that she considers her measurements to be private, and the media considers them to be irrevelant.
fairly accurate. the protest scene is acted out to be as accurate as possible
