Convert a molecule to an entity:

Convert colors to entities:

Convert undirected graphs to entities:

Convert a quantity to a physical constant:

Convert a Wolfram Language symbol to an entity:

Verify that all small graphs in GraphData give entities with canonical names equivalent to their standard names:

For suitable graph entities, FromEntity can be used to effectively "reverse" ToEntity:

This is similar for suitable character entities:

When a GraphData standard name is known, ToEntity is equivalent to the GraphData "Entity" property:

The result of ToEntity is typically Entity["type","canonicalname"]:

The canonical name of a character entity is typically the value returned by ToCharacterCode:

Entities may not exist for all possible Wolfram Language objects of appropriate type:

Some inputs may have multiple representations available:

The second argument can be used to specify to which type the input should be converted:

Specifying different arguments to same symbol may result in different "MathematicalFunction" entities:

Check that the following embeddings all correspond to the cubical graph:

Convert a range of special characters to entities:
