Winals to Hours (winal to h)
1 winal equals 480 hours exactly.
How to convert winals to hours
To convert winals to hours, multiply the number of winals by 480. This factor is exact. To go the other way, multiply hours by 0.002083333333 (rounded).
hours = winals × 480
Example: 10 winals = 4,800 hours.
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
Winal (winal)
20 days, the Maya 'month' of the Long Count.
A winal, also spelled uinal, is a block of 20 days and the second-smallest step in the Maya Long Count. It is often likened to a month, though it has nothing to do with the moon. Twenty kʼin fill one winal, which matches the 20 named days that cycle through the Maya sacred calendar and the 20-day months of the civil year.
On monuments the winal is the fourth number in a Long Count date, ahead of the kin. Its count runs from 0 to 17 and not to 19, because 18 winals make one tun of 360 days. This is the point where the otherwise base-20 system departs from pure powers of twenty. One carved example is a full-figure winal sign on Stela D at Copan.
At 20 days, a winal equals 1,728,000 seconds and is a little under three weeks. No modern calendar unit corresponds to it closely, and it is an exact count of days with no ambiguity about its size.
1 winal = 1,728,000 seconds (exactly).

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).
