h
Lowercase alphabet's eighth
H is the eighth letter of the English alphabet.
In text messages and online chat, h by itself is sometimes a typo or the result of accidentally sending before finishing.
In chemistry, lowercase h represents Planck's constant.
In measurements, h abbreviates hour: The recipe takes 2 h. (Capitalized H is the chemical symbol for hydrogen.)
