That's Right. The Metric system was invented in the UK by John Wilkins in 1668.
A hundred and twenty (120) years before the French adopted the system.
He detailed a system which would have units based on internationally agreed universal measurements, and based on decimal numbers (10, 100...etc).
This means that, realistically the anti-metric campaaigners have no grounds whatsoever to resist the metric system... They say the metric system is "foreign" .. but in fact, the Roman Imperial System is what's foreign.
It's a shame we didn't adopt the metric system back then!
