  2. Geographic coordinate conversion - Wikipedia

    en.wikipedia.org/wiki/Geographic_coordinate...

    degrees and decimal minutes: 40° 26.767′ N 79° 58.933′ W; decimal degrees: +40.446 -79.982; There are 60 minutes in a degree and 60 seconds in a minute. Therefore, to convert from a degrees minutes seconds format to a decimal degrees format, one may use the formula

  3. Minute and second of arc - Wikipedia

    en.wikipedia.org/wiki/Minute_and_second_of_arc

    The concepts of degrees, minutes, and seconds—as they relate to the measure of both angles and time—derive from Babylonian astronomy and time-keeping. Influenced by the Sumerians, the ancient Babylonians divided the Sun's perceived motion across the sky over the course of one full day into 360 degrees.

  4. Clock angle problem - Wikipedia

    en.wikipedia.org/wiki/Clock_angle_problem

    The angle is typically measured in degrees from the mark of number 12 clockwise. The time is usually based on a 12-hour clock. A method to solve such problems is to consider the rate of change of the angle in degrees per minute. The hour hand of a normal 12-hour analogue clock turns 360° in 12 hours (720 minutes) or 0.5° per minute.

  5. Decimal degrees - Wikipedia

    en.wikipedia.org/wiki/Decimal_degrees

    Decimal degrees (DD) is a notation for expressing latitude and longitude geographic coordinates as decimal fractions of a degree. DD are used in many geographic information systems (GIS), web mapping applications such as OpenStreetMap , and GPS devices.

  6. Degree (angle) - Wikipedia

    en.wikipedia.org/wiki/Degree_(angle)

    With the invention of the metric system, based on powers of ten, there was an attempt to replace degrees by decimal "degrees" in France and nearby countries, [note 3] where the number in a right angle is equal to 100 gon with 400 gon in a full circle (1° = 10 ⁄ 9 gon). This was called grade (nouveau) or grad.

  7. Madhava's sine table - Wikipedia

    en.wikipedia.org/wiki/Madhava's_sine_table

    As an example, let A be an angle whose measure is 22.50°. In Madhava's table, the entry corresponding to 22.50° is the measure in arcminutes, arcseconds and sixtieths of an arcsecond of the angle whose radian measure is the value of sin 22.50°, which is 0.3826834; multiply 0.3826834 radians by 180/ π to convert to 21.92614 degrees, which is

    Wisconsin led 39-37 at halftime after both teams went 11 for 25 from the field in the first 20 minutes. Marquette took control after the break, making its first two 3-pointers and taking a 53-47 ...

  9. Right ascension - Wikipedia

    en.wikipedia.org/wiki/Right_ascension

    Since a complete circle contains 24 h of right ascension or 360° (degrees of arc), ⁠ 1 / 24 ⁠ of a circle is measured as 1 h of right ascension, or 15°; ⁠ 1 / 1440 ⁠ of a circle is measured as 1 m of right ascension, or 15 minutes of arc (also written as 15′); and ⁠ 1 / 86400 ⁠ of a circle contains 1 s of right ascension, or 15 ...
