MEASURING LOGS

The Brereton method is the most commonly used method for measuring logs.

Brereton can also be applied for imperial measure. The Brereton method is used to calculate log volume by measuring the length of the log in metres and the diameter under bark at each end of the log in centimetres.

Length

1. Measure the length of the log in metres from the base to the crown end of the log.

2. Measure the shortest distance between butt and crown ends.

3. Record length to the nearest 0.2 metres (20 centimetres) rounded down.

Diameter

1. Measure diameter under bark in centimetres at each end of the log.

2. Measure two diameters at each end.

3. Measure the shortest diameter first (d1), then the second diameter (d2) at 90 degrees to   

     the first.

4. Repeat two diameter measurements at the other end of the log (d3 and d4).

5. Each line measurement must pass through the centre of the end of the log.

6. Record diameters in centimetres, rounding down to the nearest centimetre.

7. Mark the points where the measurements are made on each end of the log.

Records

1. Enter log length (L)

2. Enter all four diameter measurements (d1, d2, d3, d4) on the form.

Add all four measurements together and divide by 4 to find the mean diameter (D) of the      log.

3. D = (d1+d2+d3+d4) ÷ 4 centimetres

4. Calculate volume (V) by using volume tables or the formula:

V = Π ÷ 4 x D2 x L x 0.0001 cubic metres

0.7854 x D2 x L x 0.0001 cubic metres                                 V = volume of log in m3
