A meter is 39" so maybe around 8-10". Metric is easier then our system. Military i think uses metric
Are you serious?
It's the metric system which apparently the ENTIRE WORLD uses except the U.S of A.
I hear this a lot and I believe it to be incorrect. When I watch BBC shows they are often using miles, pints, stone, pounds, and gallons, so I don't think it's the ENTIRE WORLD except the USA. At the very least the UK uses it too.
What's really confusing is the car stuff, where cars are rated in miles per gallon yet petrol seems to be sold in liters (or "litres" I guess).
The kind that is used by pretty much the entire world. The kind that is more precise, more consistent, and easier to learn.
