When did the pound avoirdupois replace the troy pound as the UK standard?
Some sources say 1841, others say it was the Weights and Measures Act of 1878. A reliable source would be helpful.
And please don't tell me when the troy pound was abolished, since that is not the question. The question is about the UK primary weight standard.

The Weights and Measures Act of 1878 abolished the troy pound as of 1st January 1879. However, troy ounces are still used for weighing precious metals and gems.
