Use this fecal-egg-count conversion to calculate eggs per gram from a named quantitative method with the correct chamber, dilution, sample mass, and counting convention.

Eggs counted

Required integer input.

Chamber factor

Optional integer input.

Compute fecal egg counts in eggs per gram with the documented simple McMaster form: eggs counted in one chamber grid multiplied by the chamber factor, fifty with standard dilution adjustment. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.^[1]

Eggs per gram

The resulting eggs per gram returned as a number.

• Egg counts vary with sampling, mixing, flotation solution, chamber loading, detection limit, species, shedding, storage, and operator technique. They do not directly equal parasite burden or establish treatment need.
• Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Follow the validated laboratory protocol, run replicates and controls, identify parasites where possible, and interpret results with clinical and resistance-testing context.

• Flotac Two-Chamber EPG

  Compute Flotac eggs per gram as the summed egg counts of both chambers multiplied by the flotation factor divided by two.

• Kato-Katz Factor Converter

  Convert Kato-Katz slide egg counts to eggs per gram using the template factor; the standard forty one point seven milligram template gives a multiplication factor of twenty four.

• Anthocyanin Content

  Compute anthocyanin content in micrograms per gram of dry mass as the corrected absorbance divided by the dry mass times an extinction scale factor that defaults to one hundred; apply any baseline correction to the absorbance upstream before passing it in.
