A certain number of frequently used sites have their own templates for the external link:

The right arrow → and the equilibrium sign ⇌ are available from the codes → and {{unicode|⇌}} respectively. The use of the {{unicode}} template is recommended for ⇌ because of a bug in some versions of Internet Explorer. The equivalent left-facing signs are ← (←) and ⇋ ({{unicode|⇋}}). An alternative ⇌ sign is available as template:eqm.

The double-headed arrow ↔ for canonical forms is available from the code ↔.

• °C degrees centigrade

The center dot for hydrates etc. is available from the code ·.

• The minus sign (longer than a normal hyphen) is available form the code − but does not reproduce well on some versions of Internet Explorer.
• The multiplication sign × (e.g. for powers of ten) is available from the code ×.
• The symbols for Planck's constant, ℎ and ℏ, are available from the codes {{unicode|&#8462;}} and {{unicode|&#8463;}}: the use of the {{unicode}} template is recommended because of a bug in some versions of Internet Explorer.
• [[Å]] for angstrom
