CFU Calculator

Convert mass (mg) of lyophilized culture to estimated CFU, based on typical density assumptions.

Mass to CFU Estimator

Note: JavaScript is disabled. To estimate CFU from mass, multiply the milligrams by the typical density factor (usually 100 Billion to 200 Billion CFU per gram for pure lyophilized cultures). For example, 10mg of pure culture at 100B CFU/g = 1 Billion CFU.

Culture Density Assumption:

*Assumes pure culture without excipients or prebiotics included in the mass. This is an estimation tool.
