Hour

The hour (common symbol: h or hr) is a unit of measurement of time. In modern usage, an hour comprises 60 minutes, or 3,600 seconds. It is approximately 1/24 of a mean solar day.

An hour in the Universal Coordinated Time (UTC) time standard can include a negative or positive leap second, and may therefore have a duration of 3,599 or 3,601 seconds for adjustment purposes.

Although it is not a standard defined by the International System of Units, the hour is a unit accepted for use with SI, represented by the symbol h.

Famous quotes containing the word hour:

    If its individual citizens, to a man, are to be believed, it always is depressed, and always is stagnated, and always is at an alarming crisis, and never was otherwise; though as a body, they are ready to make oath upon the Evangelists, at any hour of the day or night, that it is the most thriving and prosperous of all countries on the habitable globe.
    Charles Dickens (1812–1870)

    Ah, Faustus,
    Now hast thou but one bare hour to live,
    And then thou must be damned perpetually!
    Stand still, you ever-moving spheres of heaven,
    That time may cease and midnight never come!
    Fair Nature’s eye, rise, rise again and make
    Perpetual day; or let this hour be but
    A year, a month, a week, a natural day,
    That Faustus may repent and save his soul!
    Christopher Marlowe (1564–1593)

    I had rather munch a crust of brown bread and an onion in a corner, without any more ado or ceremony, than feed upon turkey at another man’s table, where one is fain to sit mincing and chewing his meat an hour together, drink little, be always wiping his fingers and his chops, and never dare to cough nor sneeze, though he has never so much a mind to it, nor do a many things which a body may do freely by one’s self.
    Miguel De Cervantes (1547–1616)
