 This SI unit is named after Joseph Henry. As for all SI units whose names are derived from the proper name of a person, the first letter of its symbol is uppercase (H). But when an SI unit is spelled out, it should always be written in lowercase (henry), unless it begins a sentence or is the name "degree Celsius". — Based on The International System of Units, section 5.2.
