# Newton's Formula Calculator

Calculate the volume of a log using Newton's Formula.

One calculator for Imperial units and one for Metric units.

Newton's formula is the standard against which other cubic formula's are compared. The top, middle and base diameters are used with the log length for the determination of cubic volume.

For imperial units the volume is in cubic feet.

For metric units the volume is in cubic metres.

diameter small end + diameter large end / 2 = DIB mid section
