"Measuring of Roundwood" as recommended by the Timber Measurement Council

Measuring log volume using small and large end diameter measurements.

*Small end - large end diameter measurement may be used for all tree species on logs with a top diameter of ≥ 3 cm and length ≤ 6.5 m*.

The diameter is measured 10 cm from each end of the log, with the exception of the butt end of a butt log, where the measurement is taken 50 cm from the end.

##### Formula used:

V = π ÷ 4 * L[cDl² + (1- c)Dt²]where:

V = the log volume in cubic metres

L = length of the log in metres

c = constant

Dt = small end diameter taken 10 cm from end of log

Dl = large end diameter taken 10 cm from end of log/ taken 50 cm from the end of a butt log

### Using Small and Large Diameters

#### Calculation

- the log length in metres
- top end diameter measured 10 cm in from top end of log in centimetres
- large end diameter measured 50 cm in on a butt log, 10 cm in on other logs

#### Result

- volume of log in cubic metres
