We reproduce a rounded figure here from the 2013 CIAAW report, but the 2000 report (https://www.ciaaw.org/pubs/EXER-2000.pdf) included a more precise figure before rounding.

The final sentence in the first paragraph states that uranium can be eaten and is an extremely dense source of calories. This is patently false; uranium is toxic, the energy referred to here is the energy released upon fission and hence not usable by the human body, and the citation used says little if anything to support the statement. Please remove the sentence entirely. [[Special:Contributions/82.0.251.175|82.0.251.175]] ([[User talk:82.0.251.175|talk]]) 13:05, 11 December 2023 (UTC)
