Measurement of round timber for sale purposes in Ireland.
The volume of Irish logs is calculated using Huber's formula.
Diameters are measured mid-length of the log over bark in centimetres (cm)
Lengths are measured in metres (m) to the nearest centimetre.
A log whose length is greater than 20 metres has to be divided into two lengths for the purpose of calculating the log volume.
V = (π * Dm²) ÷ 40000 * LV = volume in cubic metres (m³)
V = Dm² * L * 0.00007854V = volume in cubic metres (m³)
