A kilogram is the SI base unit of mass, defined since 2019 by fixing the Planck constant.

What does 1 dalton represent?

One dalton equals one twelfth the mass of a carbon-12 atom and expresses atomic or molecular mass.

Why convert kilograms to daltons?

To express mass at an atomic or molecular scale for scientific fields like chemistry and biochemistry.

What Is This Tool?

This unit converter tool transforms mass measurements from kilograms, the standard SI unit for mass, into daltons, which are used to express atomic and molecular masses. It is designed to support conversions relevant in scientific fields such as chemistry and biochemistry.

How to Use This Tool?

Enter the mass value in kilograms that you want to convert.
Select kilogram as the input unit and dalton as the output unit.
Click the convert button to see the equivalent mass in daltons.

Key Features

Converts kilogram (kg) to dalton (Da) accurately using standardized constants.
Supports understanding mass at both macroscopic and atomic scales.
Browser-based and easy to use for scientific and educational purposes.

Examples

2 kg is equal to approximately 1.20443472867 × 10²⁴ daltons.
0.5 kg converts to about 3.011086821675 × 10²³ daltons.

Common Use Cases

Reporting atomic and molecular masses in chemistry and physical chemistry.
Expressing masses of proteins and peptides for biochemistry and proteomics studies.
Describing monomer and oligomer masses in polymer science and mass spectrometry.

Tips & Best Practices

Use the tool to relate everyday masses to atomic scale units for scientific interpretation.
Verify unit selections before conversion to ensure accurate results.
Understand that the dalton is suited for atomic/molecular scale and not large mass measurements.

Limitations

Dalton's extremely large numerical values make it unsuitable for typical large-scale mass measurement.
High precision calibrations require adherence to standard constants and careful instrumentation.
