## Colony Forming Unit of Bacteria Solution

STEP 0: Pre-Calculation Summary
Formula Used
colony_forming_unit_per_ml = (No. of Colonies*Dilution Factor)/Volume of Culture Plate
CFU = (nc*DF)/vc
This formula uses 3 Variables
Variables Used
No. of Colonies- No. of Colonies is a group of bacteria, fungi, and other microorganisms grown on a solid agar medium.
Dilution Factor- Dilution Factor is the factor by which the stock solution is diluted.
Volume of Culture Plate - Volume of Culture Plate is the the amount of a substance occupying a particular volume of culture plate. (Measured in Cubic Meter)
STEP 1: Convert Input(s) to Base Unit
No. of Colonies: 10 --> No Conversion Required
Dilution Factor: 10 --> No Conversion Required
Volume of Culture Plate: 10 Cubic Meter --> 10 Cubic Meter No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
CFU = (nc*DF)/vc --> (10*10)/10
Evaluating ... ...
CFU = 10
STEP 3: Convert Result to Output's Unit
10 Cells per Liter --> No Conversion Required
10 Cells per Liter <-- Colony Forming Unit per ml
(Calculation completed in 00.000 seconds)

### Colony Forming Unit of Bacteria Formula

colony_forming_unit_per_ml = (No. of Colonies*Dilution Factor)/Volume of Culture Plate
CFU = (nc*DF)/vc

## What is CFU?

A colony forming unit, or CFU, is a unit commonly used to estimate the concentration of microorganisms in a test sample. The number of visible colonies (CFU) present on an agar plate can be multiplied by the dilution factor to provide a CFU/ml result.

## How to Calculate Colony Forming Unit of Bacteria?

Colony Forming Unit of Bacteria calculator uses colony_forming_unit_per_ml = (No. of Colonies*Dilution Factor)/Volume of Culture Plate to calculate the Colony Forming Unit per ml, The Colony Forming Unit of Bacteria formula is defined as the measure of viable bacterial or fungal cells. CFU measures only viable cells. Colony Forming Unit per ml is denoted by CFU symbol.
