Measuring Circumference
If your wheel size is not listed on the GPSport 260 Pro for selection, you
can go to
User Define
to manually enter your circumference.
To measure your circumference, choose Method A or B and follow the
steps described and illustrated below. Or you can consult your bike
dealer for information of the bike circumference.
Method A:
You can calculate the circumference of your bike by simple math as
following formula.
Step 1.
Measure the diameter. The diameter of the wheel (wheel
height) is the distance across a circle through its center.
Step 2.
Calculate the circumference. Multiply
the diameter of the wheel height by pi.
If the diameter of the wheel (wheel
height) is 500 millimeters across, then
circumference would be 500 times 3.14
or 1570 millimeters.
Note: Please
use the metric system for
entering the circumference value. Convert the value if the
measurement is in imperial system. For example, when the
diameter of the wheel is 20 inches, the circumference would
be 20 times 25.4 times 3.14 or 1595.12 millimeters.
