About these units
Hour (h)
60 minutes or 3,600 seconds, one twenty-fourth of a mean solar day.
Egyptian astronomers gave us the twelve. Coffin lids from about 2150 BC show the night divided into exactly 12 intervals, tied to the rising of star groups called decans, and the day was later split into 12 hours with sundials. These were seasonal hours, a twelfth of the daylight, so a summer hour was longer than a winter one. The word itself comes from Greek hora, originally any span of time, through Latin and Old French into English in the 13th century.
Equal hours of 1/24 of a day were probably first proposed by Hipparchus, and mechanical clocks made them the practical choice, since a clock showing seasonal hours had to be readjusted every morning and evening. Today the hour is exactly 3,600 seconds and is a non-SI unit accepted for use with the SI. Civil time still bends it a little: UTC hours have lasted 3,601 seconds 27 times since 1972 to keep clocks within 0.9 seconds of the Earth's rotation. In practice we use it for working shifts, travel times and electricity bills measured in kilowatt-hours.
1 hour = 3,600 seconds (exactly).

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).
