In 1617 the Dutch scientist Willebrord Snellius assessed the circumference of the Earth at 24,630 Roman miles (24,024 statute miles). Around that time British mathematician Edmund Gunter improved navigational tools including a new quadrant to determine latitude at sea. He reasoned that the lines of latitude could be used as the basis for a unit of measurement for distance and proposed the nautical mile as one minute or one-sixtieth (1/60) of one degree of latitude. As one … WebThe standard metre was the Delambre-Mechain survey-derived “one ten-millionth part of a meridional quadrant of the earth.” The gram, the basic unit of mass, was made equal to the mass of a cubic centimetre of pure water at the temperature of …
