It's been under way since the 1970s but has been very patchy. The Statute Mile is still the only legal unit for roads in the UK; Network Rail still uses miles and chains (1ch = 22yds) for distances along railways; beer may still be dispensed in "pubs" in pints and half-pints. Many people stick to feet and inches or pounds and ounces (especially if cooking using older recipe-books) in common measurements even if using the SI units at work.
the SI was replaced because the metric system was more accurate and percise.
The SI system was established in 1960.
I don't think there is such as thing as a "metric month". The metric unit of time - more precisely, the SI unit of time - is simply the second. In the Gregorian calendar, a month can have 28, 29, 30 or 31 days. You can use the length of the year - for example, the average Gregorian year has 365.2425 days - and divide that by 12, to get the average length of the month.
The centimeter as a unit of measurement has been in use since the 18th century, introduced as part of the metric system. It was officially defined in 1795 during the French Revolution, a time when a standardized system of measurement was being established.
The U.S. liquor industry officially adopted the metric system in 1989. This change was mandated by the Federal government to standardize measurements, making it easier for consumers and producers to understand and compare alcoholic beverages.
No it isn't.

In 1869Congress legalized the use of the metric system. In 1893 the Office of Weights and Measures adopted the metric system in legally defining the yard and the pound.
Sometime between the 16th and the 17th centuries.

In 1793, France adopted as its official unit of length a metre.
In 2012, the production of silver in Australia was in excess of 24k metric tons. This amount is an all-time production high and is an increase of 28% since 2001.
Of course the metric system measures time. The second is one of the seven base units.
Australia's currency went decimal on 14th February, 1966. The decimal system is easier to use than others because it based on 10. The old Imperial monetary system was based on the old English system where there were 12 pennies in a shilling and 20 shillings in a pound or, 240 pennies in a pound. Australia's system of weights and measures went metric for the same reason in about 1973 or 1974.
The decimal system refers to counting in tens and powers of tens and this system was used when Australia was colonised by Britain in 1788. Decimal coinage was introduced much later - in 1966.
