The most popular use of the term ‘score’ is in Lincoln’s speech in Gettysburg. Nowadays, a ‘score’ as a measurement of time is rarely used. People are more acquainted with the term ‘decade.’ If a decade is 10 years, how long is a score?
A score is 20 years long. The term ‘score’ originated from the Old Norse term ‘skor,’ meaning notch, mark, or incision in rock. It also originated from the Old English term ‘scoru,’ meaning ‘twenty.’
The term score may also have come from the Proto-Germanic term ‘skur,’ meaning to cut. Also, one score has come from the practice of counting sheep or cattle from one to twenty and marking a notch or ‘score’ on a stick. Another 20 sheep are counted, and a new notch is marked anew. Therefore, each mark or ‘score’ on the stick represents 20 sheep.
Lincoln’s Gettysburg address used the term, “Four score and seven years ago…” He referred to 87 years from his speech date (four score is 80 years, plus 7). Lincoln made the speech in 1863, so he referred to 1776 when the U.S. declared its independence.

How Long Is a Score?
A score is equal to 20 years. The term originated from old Nordic and English terms, ‘skor’ and ‘scuro,’ respectively. These terms refer to the number twenty.
Why Is It Called a Score?
In the Bible, the term ‘score’ was often used. The use of the term gradually diminished as languages changed and took on newer terms. Why is it called a score?
The root word of ‘score’ is a Norse word for incision – ‘skor.’ Skor refers to cuts or incisions made on a stick to keep a tally. Twenty cuts usually fill the stick.
The English term ‘score’ originated from this Norse word. In Iceland, a score is twenty too, from the term ‘skur’ from ‘sker,’ meaning to cut.
The term ‘score’ was also used in vigesimalism, an old French counting method. This method counts large numbers of items, such as sheep, using a notch in a stick for each 20.
In addition, the French word ‘vint’ refers to twenty. People use a multiple of it as a base, as in ‘vint et doze,’ which represents 32, or ‘dous vinz et diz,’ which represents 50.
Previously, the Irish, Welsh, and Gaelic people used vigesimalism. This method was later picked up by the French and English. 
The Germanic word signifies a straight mark, such as a line or scratch drawn by a sharp instrument. In English, in the 1400s, score denotes marks made on a chalkboard or wall to keep count of a customer’s drinks in a pub.
The term also applied to the ‘innkeepers bill.’ This was the source of the expression ‘settle scores’ that became popular in 1775.
By the 1670s, people made a score mark to record a point in a game. Then in 1701, a score was used to denote a printed music piece. In 1927, a score represented music composed for films.
In 1951, score acquired a new meaning, that of acquiring narcotic drugs. This term gave the word ‘score’ a negative connotation. But it evolved into the 20th century with more positive meanings, such as test score, video game score, music score, movie score, and sports game score.

How Do You Convert Score in Time Units?
It is easy to convert scores to years if you know the Conversion Factor (CF). The Conversion Factor is 20; 1 score is equivalent to 20 years. All you have to do is multiply the number of scores by 20, and you can get the number of years.
The general formula is: S x C = E 
- S = starting value
- CF = conversion factor
- E = converted result
How many years are 5 score and 5 years?
5 score x 20 (CF) = 100 years + 5 years = 105 years (answer)
If you have to convert the years to solar days, you will have to multiply the number of years with the conversion factor, which is; 1 year = 365 solar days.
105 years x 365 (CF) = 38,325 days (answer)
Consequently, when you are asked the number of scores and the number of years is a given, you have to divide instead of multiply.
How many scores are there in 38,325 days?
- 38,325/365 days (1 year) = 105 years
- 105 years/20 years = 5.25 score
How long is a score in time? A score is 20 years. The origin of the term ‘score’ is presumed to have come from the old practice of counting large herds of cattle or sheep. They count the cattle from 1 to 20 and mark a ‘score’ or notch on a stick. One mark is made for every group of 20.
A 5-notch mark or ‘score’ on the stick would then denote 100 sheep or cattle. This practice has made counting easier and more convenient during the olden times.
