Spike's Calculators

"Cubic method" log volume formula for estimating the volume of a log using one diameter small end measurement. This is one of the methods of log scaling used in Manitoba, Canada, the other one is the Smalian formula.

Cube Method: Log Volume in Cubic Metres of Tapering CylindersV = volume in cubic metres (m³)

π = 3.14159

L = length of log in metres

D = small end diameter of log in centimetres

length, are entered as 3.5 m logs.

a log 3.4 m in length is entered as 3.3m

a log 3.61 is entered as 3.7m

33 cm to 35 cm diameter is entered as 34cm

35.1 cm diameter is entered as 36 cm

- log length in metres
- diameter small end in centimetres
