The CFU calculator online allows you to estimate the total number of bacteria per unit __area__. Our efficient cfu/ml calculator proves a valuable tool to estimate the number of colonies of weight and volume.

## What is CFU?

The CFU stands for the colony forming unit.

**“It is the unit that is used to estimate the number of microbial cells like fungi, bacteria, and viruses”.**

The cell statistics can be simplified with this unit because individual cells are very small and some may be dead whereas others are alive.

## The CFU Counting:

The bacterial concentration is the measurement of the number of colonies. The total number of bacteria per unit __weight__ or volume is their bacterial concentration.

You can calculate the CFU/ml by multiplying the total count of colonies by the dilution factor and then dividing by the volume of a culture plate.

## CFU/ml Formula:

CFU measures only viable cells of bacteria or fungi in a sample. The CFU calculator determines the bacterial concentration with the help of the following cfu formula:

$$ CFU = \dfrac{(n_c \times DF)}{V_c} $$

**Where:**

nc = number of colonies

Df = Dilution factor

Vc = volume of a culture plate

## How To Calculate CFU?

The CFU/ml can be calculated easily with the help of a CFU calculator. Consider an example to make it easier to understand.

### Example:

Let us assume that a plate of 0.01 m^3 dilution yielded a count of 12 colonies with 7 dilution factors. Then the number of bacteria in the 1 ml of the original sample is calculating CFU as follows.

**Given Data:**

- No. of colonies [nc] = 12
- Dilution factor [DF] = 7
__Volume__of culture plate [vc] = 10 liters OR 0.01 m^3

#### Solution:

The cfu ml calculation formula is as follows:

$$ CFU = \dfrac{(n_c \times DF)}{V_c} $$

$$ CFU = \dfrac{(12 \times 7)}{0.01} $$

$$ CFU = \dfrac{84}{0.01} $$

$$ CFU = 8400 m³ $$

**CFU in other units: **

CFU Cells per CFU Cells per | 8.4 cells/L |

CFU Cells per Microliter | 8.4E-6 cells/µL |

CFU Thousand Cells per Microliter | 8.4E-9 K/µL |

The cfu g calculation is simple to convert as 10g is equal to 10 ml, and so on.

## FAQs:

### What Is The Number Of Cells In 1 CFU?

The CFU assumes that every colony is separate and is founded by a single viable microbial cell.

**1 CFU = 1000 live cells**

The CFU calculations indicate the measurement in the form of units and in the number of colonies that can grow well on the plate.

### How Many CFU/ml Is In Urine?

There is 100,000 CFU per ml of bacteria are available

How Many Bacteria Are In a Colony?

A cluster of at least 50 cells is known as a colony which is determined by the CFU calculation formula.
