![]() Hour as a time measurement unit is extensively used in science and is applied for defining various related measurement units like kilometers per hour, ampere-hour, kilowatt-hour, etc. Though the history of using an hour as a part of solar day is believed to be starting from the epochs of Ancient Egypt, the concept of an hour as we know it now emerged in the early 13 th century, when scientists in Ancient Greece came up with the idea of dividing a solar day exactly into 24 equal parts. The unit is used and recognized by SI and has the symbol of h. Hour is a common time measurement unit equal to 60 minutes. Minute is also a unit used in geometry for measuring angle, as well as for defining latitude and longitude of a point on the surface of earth. To convert to decimal hours, add (minutes 60) to the hours number. This measurement unit is considered to be relatively new (especially comparing to the ones of hour or second), and it starts its history only in the Middle Ages, when the first water powered more precise time keeping devices were invented instead of common solar or sand clocks. ![]() Minute is a unit of time measurement that is equal to 1/60 of an hour. It can be used at any time as an offline tool, when you need to convert minutes to hours. Below on the webpage, you can find a minutes to hours conversion table. ![]() This is especially handy if you have large values of minutes to be converted to hours. History/origin: The term "minute" is derived from the Latin "pars minuta prima" which means the "first small part." The minute was originally defined as 1/60 of an hour (60 seconds), based on the average period of Earth's rotation relative to the sun, known as a mean solar day.Ĭurrent use: The minute, as a multiple of the second, is used for all manner of measurements of duration, from timing races, measuring cooking or baking times, number of heart beats per minute, to any number of other applications.It is probably one of the most common types of time conversion which is done every day by many people, either in their minds or by using minutes to hours converter like this. If we want to calculate how many Hours are 45 Minutes we have to multiply 45 by 1 and divide the product by 60. However, minutes are not a decimal number of hours, i.e. Under Coordinated Universal Time, a minute can have a leap second, making the minute equal to 61 rather than 60 seconds. Usage of fractions is recommended when more precision is needed. Hours and minutes are two different units that measure time. Minuteĭefinition: A minute (symbol: min) is a unit of time based on the second, the base unit of the International System of Units (SI). Durations starting from 30 minutes (half an hour) are commonly used colloquially. Most forms of employment require a certain number of hours worked per day, with compensation being based on the measured or expected hours worked. It is believed that the custom of dividing the cycle of day and night into 24 periods began with the ancient Egyptians.Ĭurrent use: The hour is used globally as a unit of time. There have been many definitions of the hour throughout history based on culture or region, such as the hour being divided into 1/12 of a period daylight or darkness. History/origin: The term "hour" is derived from the Anglo-Norman "houre," which was in use around the 13 th century. Since there are 60 minutes in one hour, thats the conversion ratio used in the formula. In Coordinated Universal Time, a negative or positive leap second may be incorporated to keep the hour within 0.9 seconds of universal time, making an hour either 3,599 or 3,601 seconds in some cases. The time in hours is equal to the time in minutes divided by 60. convert 360 minutes into Nanoseconds, Microseconds, Milliseconds, Seconds, Hours, Days, Weeks, Months, Years, etc. Definition: An hour (symbol: h) is a unit of time conventionally defined as 1/24 of a day and 3,600 seconds. ![]()
