Ħ (minuscule: ħ) is a letter of the Latin alphabet, derived from H with the addition of a bar. It is used in Maltese for a voiceless pharyngeal fricative consonant (corresponding to the letter heth of Semitic abjads: Arabic: ح, Hebrew: ח). Lowercase ħ is used in the International Phonetic Alphabet for the same sound.
In Unicode, the special character ℏ (U+210F), represents the reduced Planck constant of quantum mechanics.[1] In this context, it is pronounced "h-bar".
The lowercase resembles the Cyrillic letter Tshe (ћ), or the astronomical symbol of Saturn (♄).
A white uppercase Ħ on a red square was the logo of Heritage Malta until 2022.[2]
It is used as the symbol for Hedera Hashgraph's native cryptocurrency, HBAR.[3]
