RWC Percent
Compute relative water content as (fresh mass - dry mass) / (turgid mass - dry mass) times 100, requiring the turgid mass to exceed the dry mass and the fresh mass to lie between them.
Description
Compute relative water content as (fresh mass - dry mass) / (turgid mass - dry mass) times 100, requiring the turgid mass to exceed the dry mass and the fresh mass to lie between them.
RWC Percent is a focused biology tool that compute relative water content as (fresh mass - dry mass) / (turgid mass - dry mass) times 100, requiring the turgid mass to exceed the dry mass and the fresh mass to lie between them. It calculates locally from the values you enter and exposes the result without changing the source observations.1
When to use RWC Percent
Use RWC Percent when you need to compute relative water content as (fresh mass - dry mass) / (turgid mass - dry mass) times 100, requiring the turgid mass to exceed the dry mass and the fresh mass to lie between them. Enter Dry mass, Fresh mass, and Turgid mass using the definitions and units below so the result can be reproduced.
- Dry mass
- Dry mass in grams.
- Fresh mass
- Fresh mass in grams; must lie between the dry and turgid masses.
- Turgid mass
- Turgid mass in grams; must exceed the dry mass.
How RWC Percent calculates the result
The published tool contract uses this rule: Compute relative water content as (fresh mass - dry mass) / (turgid mass - dry mass) times 100, requiring the turgid mass to exceed the dry mass and the fresh mass to lie between them.
- Relative water content
- Relative water content percentage between 0 and 100.
Limitations of RWC Percent
The calculation does not propagate measurement uncertainty, sampling error, or biological and chemical variability.
Alternative or Complementary measurements
Retain the original Dry mass, Fresh mass, and Turgid mass values and their units alongside the result. RWC Dewpoint Variant is useful when you instead need to compute relative water content with dew point hygrometer naming as (fresh mass - dry mass) / (turgid mass - dry mass) times 100, requiring the turgid mass to exceed the dry mass and the fresh mass to lie between them. LDMC Percent provides another view by helping you compute leaf dry matter content as a percentage from oven dry leaf mass over turgid fresh leaf mass.
