Score to Seconds (score to s)
1 score equals 631,139,040 seconds exactly.
How to convert score to seconds
To convert score to seconds, multiply the number of score by 631,139,040. This factor is exact. To go the other way, multiply seconds by 1.584436925×10⁻⁹ (rounded).
seconds = score × 631,139,040
Example: 10 score = 6,311,390,400 seconds.
Months and years are not constant. This site uses the average Gregorian year of 365.2425 days, so one 'year' converts to 365.2425 days, not 365; use 'common year' for exactly 365 days.
About these units
Score (score)
Twenty years. Familiar from 'four score and seven years ago' (87 years) in the Gettysburg Address.
Score meant a notch cut on a tally stick. The word is related to Old Norse skor, and because people often counted in twenties, every twentieth notch was cut larger, so the word came to mean twenty. As a unit of time, a score of years is 20 years, about 631 million seconds on the Gregorian calendar.
The best known use is the opening of the Gettysburg Address, delivered on 19 November 1863, where Lincoln spoke of four score and seven years ago. That is 87 years, which counted back from 1863 reaches 1776 and the Declaration of Independence. Wikipedia notes that the word also appears loosely as scores of, meaning a large unspecified number. A score is two decades, and five scores make a century.
1 score = 631,139,040 seconds (exactly).

Second (s)
The SI base unit of time, defined by the radiation frequency of the cesium-133 atom: 9,192,631,770 cycles per second.
Our word second is a leftover of Latin. Medieval scholars divided a degree, and later the hour, into 60 parts called pars minuta prima, the first small part, and divided those again into pars minuta secunda, the second small part. NIST traces the roots further back: Babylonian and Greek astronomers split the circle into 360 degrees, and around 150 C.E. Ptolemy split each degree into 60 minutes and each minute into 60 seconds. Clocks that could show seconds appeared only in the later 16th century, and Christiaan Huygens's pendulum clock of 1656 was the first able to keep time accurately to the second.
For most of history the second was a fraction of a day, and in 1956 it was redefined as a fraction of the tropical year, a definition the SI took over in 1960. In 1967 the 13th CGPM switched to atoms: 9,192,631,770 periods of the radiation tied to a hyperfine transition of caesium-133. The 2019 SI revision restated this by fixing the caesium frequency at 9,192,631,770 hertz. NIST reports that commercial caesium clocks stay within about a three-millionth of a second per year, and experimental clocks based on other atoms are roughly ten thousand times more precise.
The second is the reference unit for time on this site.
