Latitude, usually denoted symbolically by the Greek letter phi, , gives the location of a place on Earth north or south of the equator. Lines of Latitude are the horizontal lines shown running east-to-west on maps.

Converting Latitude/Longitude to Universal Transverse Mercator (UTM)
On October 5th, 1996, I posted a request on sci.geo.geology and sci.geo.satellite-nav asking about conversion formulas between latitude/longitude and UTM coordinate systems.
Latitude (Lat): A position's distance north or south of the equator, measured by degrees from zero to 90. One minute of latitude equals one nautical mile.

Universal Transverse Mercator (UTM).
Here's an explanation of UTM: Mercator, Transverse Mercator, and Universal Transverse Mercator.
Latitude
The latitude of a point on the earth's surface is given by the point's angular distance north or south of the equator.
Latitudes and Longitudes
Although the Earth is a three-dimensional object, when supposed spherical its surface has a constant radius, so any point on it is uniquely identified using a polar two-coordinate system.
Latitude and Longitude
The second is more complex and involves supplying information about latitude and longitude for the area being mapped.
Latitude - The angular distance, usually measured in degrees north or south of the equator. Lines of latitude are also referred to as parallels.
latitude-longitude
A spherical reference system used to measure locations on the Earth's surface. Latitude and longitude are angles measured from the Earth's center to locations on the Earth's surface.

Latitude: The first component of a spherical coordinate system used to record positions on the earth's surface. Latitude indicates the angular distance north or south of the earth's equator measured through 90 degrees. (See Longitude) ...
Latitude is the angle measured from the earth's center north or south of a given point on the earth's surface - defined by geometric center of the earth's spin axis, the equator, lying at 000° latitude.
Latitude and longitude are easily estimated for any location, but elevation must also be provided to interrogate the interpolated climatic relationships. A digital elevation model was prepared by Zuo et al.

latitude and longitude on a sphere (or ellipsoid of revolution--more about that later) or
Cartesian coordinates (x, y).
latitude/longitude (Lat/Long) The fundamental geographic coordinate system, consisting of parallel lines of latitude circling the globe in an east-west direction and north-south lines of longitude (meridians) that converge at the poles.
Latitude and longitude representing the geographic coordinates f, l of a point P with respect to the selected reference surface. They are always given in angular units (e.g. City hall Enschede: f = 520 13' 26.2" N, l = 60 53' 32.1" E).
Latitude is the angle measured at the centre of the earth northwards (or southwards) between the equator and the position of a point on the earth's surface.
latitude-longitude
A reference system used to locate positions on the earth's surface. Distances east-west are measured with lines of longitude (also called meridians), which run north-south and converge at the north and south poles.
latitude (j) - measures angle between the point and the equator along the meridian1

Latitude
A north/south measurement of position perpendicular to the earth's polar axis.

LATITUDE
The angular distance north or south between a point on the Earth's surface and the Equator. The distance is measured with reference to an idealised, spheroid-shape of the Earth.
Latitude is the system of determining location on the surface on the earth along a given north-south line. Measured in degrees north and south of the equator, it was first used by Greek geographers over 2000 years ago.
Latitude - The angle, measured from the Earth's geometric center, between the equator and a point on or above the Earth's surface. Latitudes are also referred to as parallels.

Latitude: The angular distance of a location north or south of the equator.
At mid-latitude locations, the geostationary satellite signals are received from fairly low elevation angles--often below 30 degrees--and thus are prone to signal attenuation and blockage by obstructions.
Lines of latitude and longitude are parallel intersecting at 90 degrees. Meridians are equidistant. Forms a rectangular map. Scale along the equator or standard parallels is true. Simple construction.
Note: In latitude/longitude locations the position coordinates pair (east/west) has to be specified in decimal degree (not D:M:S). If not specified, the map center's coordinates will be used. Also g.region -l displays the map center's coordinates.
The lines of latitude and longitude are often projected onto flat surfaces in order to describe position on a planar map. Projecting a curved surface like that of a sphere onto a plane produces distortion.

It turns out that latitude and longitude are only two of the three pieces of information needed in order to truly understand the relationships among places.
Either collect in latitude/longitude or UTM. If lat/long, and if you use a USGS DRG or DOQ, you must change the VIEW properties in order to view these correctly on top of the base layers. If you collect in UTM, no view properties setting is required.
Inside ArcView, the latitude and longitude are calculated for each matched address.
A horizontal line encircling the earth at a constant latitude . The equator is a parallel whose latitude is 0 degrees. Digital measures of latitude are positive up to 90 degrees above the equator and negative below.
Location may be annotated by x,y, and z coordinates of longitude, latitude, and elevation, or by such systems as ZIP codes or highway mile markers. Any variable that can be located spatially can be fed into a GIS.

Bergmann's Rule: The colder the climate (thus, usually, the higher the latitude) the larger the body size of a warm blooded animal when compared to close relatives in warmer regions.
The circle on the left depicts a sphere with a radius r1 on which a coordinate system (essentially, latitude and longitude lines) has been traced. That describes expansion from an initial point (radius r0).
For example an aerial photograph may need to be stretched (orthorectified) using photogrammetry so that its pixels align with longitude and latitude gradations (or whatever grid is needed).
The easiest way to try to transfer the information onto a flat surface is to convert the geographic coordinates into an X and Y coordinate system, where x is longitude and y is latitude. This is an example of "projecting" onto a plane.
A new geo-coordinate system conversion function (Edit/Geo Coord Convert/UTM and LL) to convert between UTM coordinate system and the latitude/longitude system. This function supports most geodetic datum used around the world.
In a cylindrical projection, for example, the lines of latitude (parallels) of the selected ellipsoid are simply drawn as straight, parallel lines.
Current Loran-C receivers track three or more transmitters to provide a position fix usually computed by the receiver and displayed as latitude and longitude.
In the northern hemisphere degrees of latitude are measured from zero at the equator to ninety at the north pole. In the southern hemisphere degrees of latitude are measured from zero at the equator to ninety degrees at the south pole.
