![]() However, no consistent records of the origin for the division as 1⁄60 part of the hour (and the second 1⁄60 of the minute) have ever been found, despite many speculations. What is traceable only is that it started being recorded in the Middle Ages due to the ability of construction of "precision" timepieces (mechanical and water clocks). In contrast to the hour, the minute (and the second) does not have a clear historical background. The prime is also sometimes used informally to denote minutes of time. The SI symbols for minute or minutes are min for time measurement, and the prime symbol after a number, e.g. Although not an SI unit for either time or angle, the minute is accepted for use with SI units for both. As a unit of angle, the minute of arc is equal to 1⁄60 of a degree, or 60 seconds (of arc). In the UTC time standard, a minute on rare occasions has 61 seconds, a consequence of leap seconds (there is a provision to insert a negative leap second, which would result in a 59-second minute, but this has never happened in more than 40 years under this system). As a unit of time, the minute (symbol: min) is equal to 1⁄60 (the first sexagesimal fraction) of an hour, or 60 seconds. The minute is a unit of time or of angle. In the modern metric system, hours are an accepted unit of time equal to 3,600 seconds but an hour of Coordinated Universal Time (UTC) may incorporate a positive or negative leap second, making it last 3,599 or 3,601 seconds, in order to keep it within 0.9 seconds of universal time, which is based on measurements of the mean solar day at 0° longitude. This was finally abandoned due to the minor slowing caused by the Earth's tidal deceleration by the Moon. The Time Conversion Chart - Minutes to Decimal Hours is typically filed by the employer or the human resources department. It is helpful when calculating and recording time for work or other activities. For further calculation, (24000/1001) is used instead of. A Time Conversion Chart - Minutes to Decimal Hours is used to convert time expressed in minutes into decimal hours. For example, to convert the time code 00:17:51:13 from 23,976 fps to 25 fps, first convert the SMPTE time code to frames: 00:17:51:13 25717 frames. ![]() ![]() The minor variations of this unit were eventually smoothed by making it 1⁄24 of the mean solar day, based on the measure of the sun's transit along the celestial equator rather than along the ecliptic. To convert a timecode to a different frame rate, the total number of frames is multiplied by (target frame rate / source frame rate). Its East Asian equivalent was the shi, which was 1⁄12 of the apparent solar day a similar system was eventually developed in Europe which measured its equal or equinoctial hour as 1⁄24 of such days measured from noon to noon. It was subsequently divided into 60 minutes, each of 60 seconds. Such hours varied by season, latitude, and weather. The seasonal, temporal, or unequal hour was established in the ancient Near East as 1⁄12 of the night or daytime. This is how they are defined: HoursĪn hour (symbol: h also abbreviated hr.) is a unit of time conventionally reckoned as 1⁄24 of a day and scientifically reckoned as 3,599–3,601 seconds, depending on conditions. The units involved in this conversion are hours and minutes. For quick reference purposes, below is the hours to minutes conversion table: hours (hr) ![]()
