Conversion Equation:
From: | To: |
The conversion between grams per mole (g/mol) and Daltons (Da) is a direct 1:1 conversion. One Dalton is defined as one-twelfth the mass of a carbon-12 atom, which is equivalent to 1 g/mol. This conversion is fundamental in biochemistry and molecular biology for expressing molecular weights.
The calculator uses the simple conversion equation:
Where:
Explanation: Since 1 Dalton is exactly equal to 1 atomic mass unit (amu) and 1 g/mol represents the mass of one mole of a substance in grams, the numerical values are identical when converting between these units.
Details: Accurate molecular weight conversion is essential for various scientific applications including protein characterization, drug development, biochemical research, and mass spectrometry analysis where molecular masses are frequently expressed in Daltons.
Tips: Enter the molecular weight in grams per mole (g/mol). The value must be a positive number. The calculator will instantly provide the equivalent value in Daltons (Da).
Q1: Why is there a 1:1 conversion between g/mol and Daltons?
A: The Dalton is defined such that one Dalton equals 1/12 the mass of a carbon-12 atom, which corresponds exactly to 1 g/mol when considering Avogadro's number.
Q2: Are Daltons and atomic mass units (amu) the same?
A: Yes, Daltons and atomic mass units are equivalent terms and represent the same unit of measurement for atomic and molecular masses.
Q3: When should I use Daltons vs g/mol?
A: Daltons are typically used for individual molecules or atoms, while g/mol is used for molar quantities. However, numerically they are identical.
Q4: Does this conversion work for all molecules?
A: Yes, this conversion is universal and applies to all atomic and molecular weights regardless of the substance.
Q5: How precise is this conversion?
A: The conversion is mathematically exact - 1 g/mol always equals 1 Dalton by definition.
