 # Acreage Measurement

Both the Rolatape® 660 and the Measure Master® 6.6 are acreage measuring wheels. The diameter of the Rolatape® 660 and the MM 6.6 is 25". Both measure exactly 6.6' for each revolution of the wheel, and the counters record the number of revolutions. For example, if the counter records 10, that means you have measured 10 revolutions, or 66'. This feature vastly simplifies the computation of acreage measurements, if you adhere to the following methods.

Measuring a Rectangle

Count the number of revolutions on one side of the rectangle and the number of revolutions on the other side. You compute the acreage in the rectangle by multiplying these two numbers and dividing by 1,000. (to divide by 1,000. move the decimal point three places to the left.)

For example, a rectangle measures 125 revolutions on its long side and 30 revolutions on its shorter side.

125 x 30 = 3,750

Divide by 1,000 (point off three decimal places to the left)

Answer: 3.750 acres

Measuring a Right-Angle Triangle

A right-angle triangle is half of a rectangle which is cut in two by the third side of the triangle.It has one 90 degree corner. So, after you obtain the area of the rectangle as described above, the half of that area is the area of the triangle.

The triangle is 125 revolutions on its long side and 30 revolutions on its short side.

125 x 30 = 3,750

Divide by 1,000 = 3.750

Divide by 2 (one half of the rectangle)

Answer: 1.875
