DEGREES MINUS MINUTES HOW TO
In this lesson we will walk through how to convert an angle from Degrees-Minutes-Seconds to Decimal Degree, as well as converting from Decimal Degree to Degrees Minutes Seconds. Therefore, when we need to convert from DMS to Decimal Degree or vice versa, all we have to do is basically divide or multiply by 60!
DEGREES MINUS MINUTES FULL
…The Ancient Babylonians used a sexagsimal systems when the calendar was based on having 360 days in a year one day was equal to one degree and a whole year was like going a full circle or 360 degrees.Īnyway, because of this, we can now say that 1 degree is equal to 60 minutes and 1 minute is equal to 60 seconds, as nicely stated by Augusta Technical College. Now finally we have to minus minutes and the hours and we will keep the outcomes on the suitable side of the. Note that our calculator requires that your latitude and longitude be in decimal format. 2) Select a multiple of ‘5’ or ’10’ for simple arithmetic. 15.3 - 15 degrees 18 minutes 0 seconds (. It can add and subtract in degrees, minutes and seconds formats. Okay, so if I have to learn it, then what is this thing all about? It supports simple mathematical operations like addition, subtraction. So, we might as well just dive right in and become smarty pants together! You never know, you may be the captain of a naval vessel or leading an expedition one day, and you’ll be glad you know your Degrees, Minutes and Seconds.
Besides, it’s in your textbook and your teacher wants you to learn it!
Yes, technology is awesome and helpful, but it’s always a good idea to know why it works. While I would have to agree that you’re probably not lost in the woods right now, the DMS method still comes in handy when we are trying to read the coordinates of a map or working with distance and position.īut why I can’t I just use an App or this really cool website like Rapidtables to convert for me? Typically, we like to use decimal degrees, like 13.16 degrees instead of 13 degrees and 10 minutes, because they make more sense to use and are easier for us to calculate.īut, when we are working with Latitudes, Longitudes, Topography, Navigation, Surveying and Metrics, it is more common to use Degrees-Minutes-Seconds (DMS) notation because minutes and seconds in degrees resemble minutes and seconds for a clock.īut I’m not lost in the woods, trying to read a map! Convert 30.263888889 angle to degrees,minutes,seconds: d integer(30. Well, believe it or not, yes, we still use this this method of measuring angles. The minutes (m) are equal to the integer part of the decimal degrees (dd) minus integer degrees (d) times 60: m integer((dd - d) × 60) The seconds (s) are equal to the decimal degrees (dd) minus integer degrees (d) minus minutes (m) divided by 60 times 3600: s (dd - d - m/60) × 3600. Traditionally, portions of a degree have been measured with minutes and seconds.ĭo we still use this anymore? Isn’t this something my parents and grandparents used?
