Use Wood Specific Gravity when you need to compute wood specific gravity as oven dry mass divided by water displacement volume in cubic centimetres. Enter Oven dry mass and Water displacement volume using the definitions and units below so the result can be reproduced.

Oven dry mass

A finite measured or assumed value, expressed in g.

Water displacement volume

A finite measured or assumed value, expressed in cm³.

The published tool contract uses this rule: Compute wood specific gravity as oven dry mass divided by water displacement volume in cubic centimetres.

Specific gravity

The calculated specific gravity.

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 Oven dry mass and Water displacement volume values and their units alongside the result. Stem Wood Density is useful when you instead need to compute stem wood density in grams per cubic centimetre as oven-dry stem mass divided by stem volume. Wood Density provides another view by helping you compute basic wood density in grams per cubic centimetre as oven-dry mass divided by fresh volume.

• Stem Wood Density

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

• Wood Density

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

• Specific Leaf Area

  Compute specific leaf area SLA in square centimetres per gram as one-sided leaf area divided by leaf dry mass.
