Base Pair to Dalton Formula
The following formula is used to calculate the molecular weight in Daltons for a given number of base pairs.
D = BP * CF
Variables:
- D is the molecular weight in Daltons
- BP is the number of base pairs
- CF is the conversion factor (Daltons per base pair)
To calculate the molecular weight in Daltons, multiply the number of base pairs by the conversion factor. The default conversion factor is typically 650 Daltons per base pair.

What is a Dalton?
A Dalton, also known as an atomic mass unit (amu), is a standard unit of mass that quantifies mass on an atomic or molecular scale. It is defined as one twelfth of the mass of an unbound neutral atom of carbon-12 in its nuclear and electronic ground state, and it is approximately equal to the mass of one nucleon (either a single proton or neutron). The Dalton is used in biochemistry and molecular biology to express the mass of large molecules such as proteins and nucleic acids.
How to Calculate Base Pair to Dalton?
The following steps outline how to calculate the molecular weight in Daltons from the number of base pairs.
- First, determine the number of base pairs (BP).
- Next, determine the conversion factor (CF), which is typically 650 Daltons per base pair.
- Finally, calculate the molecular weight in Daltons using the formula D = BP * CF.
- After inserting the values and calculating the result, check your answer with the calculator above.
