Linear Measurement

Length and Distance

Line:

Line as one dimension.

When you put tiny little dots side by side it makes a dash.

When you place dashes side by side it makes a line. 

Line may be straight or may be curved.

Line shows a distance between two points.

If you want to measure distance between to points on paper or in real life there are two major systems people use.

One is traditional or customary system and the other is metric system.

For the length or distance traditional system uses:

inches, feet, yards, miles, etc

And the metric system uses:

millimeters, centimeters, meters, kilometers, etc.

Table of Linear Measure

Traditional System

12 inches = 1 foot

3 feet = 1 yard

660 feet = 1 furlong

5280 feet = 1 mile

Table of Linear Measure

Metric System

In Metric system "meter" is the main unit.

milli......centi......deci......meter......deca......hecto......kilo.....

On the right side:

meter x 10 = decameter

meter x  100 = hectometer

meter x 1000 = kilometer

On the left side:

meter ÷ 10 = decimeter

meter  ÷ 100 = centimeter

meter ÷ 1000 = millimeter

10 millimeter = 1 centimeter

10 centimeter = 1 decimeter

10 decimeter = 1 meter

1000 millimeter = 1 meter

100 centimeter = 1 meter

10 meter = 1 decameter

100 meter = 1 hectometer

1000 meter = 1 kilometer

1 mile = 1.609 kilometers

1 kilometer = 0.621 miles

Mile is longer than Kilometer

1 inch = 2.54 centimeters

1 feet = 30.48 centimeters

1 centimeter = 0.394 inches

1 meter = 1.093 yards

1 yard = 0.914 meters

Yard is longer than Meter

Inch is longer than Centimeter
