codata is a Fortran library providing the fundamental physical constants published by the CODATA. It includes the 2022, 2018, 2014 and 2010 recommended values, allowing applications to reproduce calculations based on specific CODATA releases.
The constants are implemented as a derived type that carries: the name, the value, the uncertainty, and the unit. All the constants are provided as double precision reals. Long constant names can be aliased with shorter names.
It provides:
|
• |
CODATA 2022 constants |
|||
|
• |
CODATA 2018 constants |
|||
|
• |
CODATA 2014 constants |
|||
|
• |
CODATA 2010 constants |
|||
|
• |
Native Fortran API |
|||
|
• |
C interoperability API |
|||
|
• |
Python bindings |

Selection of an adjustment at compile time or at run time |
Fortran API
exposes the constants as derived type codata_constant_type which carries the name, the value, the uncertainty, and the unit.
C API
exposes a structure codata_constant_type that defines the same members as in Fortran i.e. the name, the value, the uncertainty, and the unit.
Python
exposes a dictionary with the keys being the name, the value, the uncertainty, and the unit.
There are two
ways to reach a constant, and they are generated from the
same source data, so they cannot disagree.
Named symbols, selected at compile time
Every adjustment is available under year-suffixed names: BOHR_RADIUS_2010, BOHR_RADIUS_2014, BOHR_RADIUS_2018, BOHR_RADIUS_2022. These are parameters in Fortran and const objects in C, so they may be used in initialisation expressions and array bounds, and are folded into the code by the compiler. Use these when the adjustment is fixed when the program is built.
The runtime accessor
codata_value(ds, q) and its companions take the adjustment ds and the quantity key q as arguments and resolve the constant at run time. Use these when the adjustment is chosen by input, or when a program must hold more than one adjustment at once, such as reading a checkpoint written under an older adjustment while computing under a current one.
The adjustment is always an explicit argument. There is no global "current adjustment" to set, so the accessors are reentrant and two adjustments can be in use at the same time.
The available adjustments are CODATA_2010, CODATA_2014, CODATA_2018, CODATA_2022, and CODATA_LATEST, which follows the most recent one and therefore changes when a new adjustment is added.
A quantity key names a physical quantity independently of the adjustment it is taken from. The keys are CODATA_Q_* in C and Python and Q_* in Fortran; the Fortran prefix is shorter because Fortran limits a name to 63 characters, which CODATA_Q_ plus the longest quantity name exceeds.
Key values never change when a new adjustment is added, so a key stored in a file remains valid.
The adjustments do not all contain the same quantities. Use codata_defined(ds, q) to test, or codata_get(ds, q) which returns NULL (a null pointer in Fortran, None in Python) for a quantity that adjustment does not contain. codata_value returns a quiet NaN in that case, never 0.0: a plausible-looking wrong number is the worst available failure mode for a constants library.
NIST renames quantities between adjustments. What CODATA 2014 calls ELECTRIC_CONSTANT is called VACUUM_ELECTRIC_PERMITTIVITY from 2018 on, and PLANCK_CONSTANT_OVER_2_PI became REDUCED_PLANCK_CONSTANT.
Every such quantity is available under both spellings in every adjustment, and both spellings share one quantity key, so code written against either name works against all adjustments.
A pair is only treated as a rename when the units are compatible and the values agree to within five standard uncertainties. Names alone are not enough: ELEMENTARY_CHARGE_OVER_H and ELEMENTARY_CHARGE_OVER_H_BAR look like a rename but differ by a factor of 2π. Quantities that were genuinely retired or genuinely added are not aliased, and are reported as undefined for the adjustments that lack them.
The latest adjustment is additionally available without the year as a suffix, as an alias meaning "current". Because that alias follows the most recent adjustment, it changes value when a new adjustment is added; use the year-suffixed names to pin to a particular adjustment. All constants are declared with the same variable name in Fortran, C, and Python.
