U/ml to ng/ml Calculator

Formula

The formula to convert U/ml to ng/ml is:

\[ ng/ml = U/ml \times MW \]

Where:

\(U/ml\) is the concentration of enzyme activity in Units per milliliter
\(MW\) is the molecular weight of the enzyme in Daltons (Da)
\(ng/ml\) is the concentration in nanograms per milliliter

What is U/ml to ng/ml Conversion?

U/ml to ng/ml conversion is a process of converting the activity of an enzyme, which is measured in Units per milliliter, to its mass concentration in nanograms per milliliter. This conversion is necessary when working with enzyme assays and biochemical calculations where both activity and mass concentration are relevant.

Example Calculation 1

Let's assume the following values:

Enzyme Activity (U/ml) = 50 U/ml
Molecular Weight (MW) = 30,000 Da

Using the formula:

\[ ng/ml = 50 \times 30,000 = 1,500,000 \text{ ng/ml} \]

The concentration is 1,500,000 ng/ml.

Example Calculation 2

Let's assume the following values:

Enzyme Activity (U/ml) = 100 U/ml
Molecular Weight (MW) = 25,000 Da

Using the formula:

\[ ng/ml = 100 \times 25,000 = 2,500,000 \text{ ng/ml} \]

The concentration is 2,500,000 ng/ml.
