Use Stem Wood Density when you need to compute stem wood density in grams per cubic centimetre as oven-dry stem mass divided by stem volume. Enter Stem dry mass and Stem volume using the definitions and units below so the result can be reproduced.

Stem dry mass

A finite measured or assumed value, expressed in g.

Stem volume

A finite measured or assumed value, expressed in cm³.

The published tool contract uses this rule: Compute stem wood density in grams per cubic centimetre as oven-dry stem mass divided by stem volume.

Stem wood density

The calculated stem wood density in g/cm³.

A ratio or percentage can conceal the scale of its numerator and denominator and becomes sensitive to measurement error when the denominator is small.

Retain the original Stem dry mass and Stem volume values and their units alongside the result. Wood Density is useful when you instead need to compute basic wood density in grams per cubic centimetre as oven-dry mass divided by fresh volume. Wood Specific Gravity provides another view by helping you compute wood specific gravity as oven dry mass divided by water displacement volume in cubic centimetres.

• Wood Density

  Compute basic wood density in grams per cubic centimetre as oven-dry mass divided by fresh volume.

• Wood Specific Gravity

  Compute wood specific gravity as oven dry mass divided by water displacement volume in cubic centimetres.

• Root Length Density

  Compute root length density RLD in centimetres per cubic centimetre of soil as root length divided by soil core volume.
