Subsequent Events [Abstract]
Subsequent Events	SUBSEQUENT EVENTSOn May 4, 2022, Emerson announced its intention to exit business operations in Russia and is exploring strategic options to divest Metran, its Russia-based manufacturing subsidiary. Emerson is committed to an orderly transfer of these assets and will support its employees through this process. Emerson's historical net sales in Russia were principally in the Automation Solutions segment and in total, represent approximately 1.5 percent of consolidated annual sales. As of March 31, 2022, Emerson's Russian operations had net assets of approximately $50 and accumulated foreign currency translation losses of approximately $145 (which will be recognized as a non-cash charge when the exit is completed). The Company is currently unable to estimate the full financial consequences of the exit due to uncertainty regarding the commercial terms of the exit and related tax impacts.
