Length Is Measured In Meters
1/1000 of a meter	.001 Meter	= 1 Millimeter (mm)
1/100 of a meter	.01 Meter	= 1 Centimeter (cm)
1/10 of a meter	.1 Meter	= 1 Decimeter
1 Meter (m)	1 Standard Unit Of Measure For Length
10 m	10 Meters	1 Decameter
100 m	100 Meters	1 Hectometer
1km	1000 Meters	1 Kilometer (km)
Area Measurement
1 Square Centimeter	= 100 Square Millimeter (mm)
1 Square Meter	= 10000 Square Centimeters
1 Are	= 100 Square Meter (sq m)
1 Hectare	= 100 Ares
1 Hectare	= 10000 sq. m
1 Square Kilometer	= 100 Hectares
1 Square Kilometer	= 1,000,000 Square Meters

 

U.S. Based System Of Measure For Length

• Outdated System Of Measure; Over Complicated

• 1 inch = 2.54 centimeters

• 1 yard = 0.9144 meters

• 1 mile = 5,280 feet = 63,360 inches

• 1 hectare = 2.471 acres = 10,000 square meters

• 39.37 US Survey Feet = 12 Meters

•  US survey foot is gradually being phased out as the maps

• U.S.G.S. Maps Are Made With UTM Projections

• Modern Maps Should Be Produced With Metric.  Look For More Modern Maps That Included The UTM Protection.

SI (System International)

• SI (System International) ; "Le Systeme international d'Unites" officially came into being in October 1960 as the world standard of measurement.

UTM

• Universal Transverse Mercator (UTM) Grid System

• UTM Coordinates Are Based On A Grid System, Which Is Based On The Meter

• UTM Is The Popular Coordinate System Used In Survey, And Mapping Applications

• UTM Coordinate System Maximizes The Benefits Of GPS Technology

• UTM Relies On Grid Zone Designations And Easting/Northing Distances, Providing One Meter Resolution

• GPS Users Can Benefit Greatly By Working With UTM.  UTM Coordinates Make It Easy For Anyone To Relate To Positioning Information Anywhere On Earth.   With the UTM System, Every Point On Earth Now Has A Precise Two-Number Address That Is Given In Meters.  To Make UTM Coordinates Faster To Work With, The Grid Was Given Large-Area Grid Identification Designators.  These Large Scale Grid Designators Makes It Faster To Know What Region On Earth The UTM Coordinates Identify.

• The UTM Coordinate System Offers Advantages Of Universal Simplicity, Speed, Precision, And Reliability Over The Previously Used Geographic Coordinate System (Latitude/Longitude).

• The Universal Transverse Mercator (UTM) Grid System Provides A Simple, Accurate And Globally Universal Method For Identifying And Giving Reference To, Every Square Geographic Location Meter On Earth

• Because UTM Measurements Are Made Directly From A Scale, They Tend To Be More Accurate Than Geographic Coordinates (Latitude/Longitude) Estimated From Geometrical Constructions.

• The Smallest Common Unit In The Geographic Coordinates System, Is The Second, Which Is Roughly Equivalent To 100 Feet Depending On Where It Is Measured; While The Smallest Unit Of Measure In The UTM System Can Be 1 Centimeter; Civilian Applications On Average Is 1 Meter With Some Equipment Capable Of Working In 10ths Of A Meter Accuracy.

• The UTM System Involves No Complicated Geometric Constructions, And In Its Basic Application, Requires As Working Tools, Only A Straightedge, A Coordinate Romer, And A Sharp Pencil.

• UTM Zone Numbers Appear In The Legend In The Lower Left Margin Of Modern USGS Topo Maps

• UTM Grid System Is Now Included On Official Modern Topo Maps Produced By The Various Governments

• A UTM Coordinate May Easily Be Found On A Map With UTM Grid Tick Marks Along Its Edges, Or With A UTM Grid Superimposed On The Map.

• A UTM Coordinate May Easily Be Found On Earth Using A GPS Device, Or A Method Of Measuring Distance In Meters; And/Or A Combination Of Both Methods.

• The UTM Coordinates Of Any Point On Earth Can Easily Be Found Using A GPS Device.  The GPS Device Can Be Used To Determine A Precise Location On Earth And Then Provide The Coordinates In UTM Format.  This UTM Coordinates Can Then Be Easily Plotted On A Modern Map.  More Advanced Methods Can Be Used To Project The UTM Grid System On Maps That Do Provide The UTM Grid System Reference.

• A UTM Coordinate May Easily Be Found On Earth Using A GPS Device, Or A Method Of Measuring Distance In Meters; And/Or A Combination Of Both Methods.
