Calculate

Total DNA Length (L) in nanometers:

The Base Pair Length Calculator is a tool designed to determine the total length of a DNA molecule based on the number of base pairs and the length of each base pair. This is especially useful in molecular biology and genetics research.

Formula

The formula to calculate the total DNA length is:
L = N * l
Where:

• L = Total DNA length
• N = Number of base pairs
• l = Length per base pair

How to Use

1. Enter the number of base pairs (N) in the first field.
2. Enter the length per base pair (l) in nanometers in the second field.
3. Click the Calculate button.
4. The result will display the total DNA length (L) in nanometers.

Example

If a DNA molecule has 3,000 base pairs, and each base pair measures 0.34 nanometers:
L = 3000 * 0.34 = 1020 nm
The total DNA length is 1,020 nanometers.
