Measure the length between any three rivets. There are 10 chains in a furlong, and 80 chains in one statute mile. Gauge the length between any 3 rivets and divide by 2 to find the pitch.

To find the cutting length, put one tip of measuring tape on the chainsaw’s edge and measure it till the bar’s merging point. Step 2 locate the corresponding step on the gauge. Measure one foot of the chain with a tape, then count the links.

Then, you use the equation for finding the length of your chain. Usually, this value is engraved on the same bar, or in any case, must be considered at the. Now, you need to measure the pitch, or the distance between the chain drive links.
