    I used to play a bit of golf so yardage is pretty easy for me. Guesstimate and accommodate for those few inches and stop down.

    As a target shooter for 40~ years, yards are ingrained in my brain for any distance over 12 1/2 or so fathoms.

    Of course. It's used every day throughout the country.

    Modern machine tools can work in either metric or imperial interchangeably, at the press of a button.

    Modern mechanical drawings normally have dimensions in both systems for the convenience of the reader.
    One system is stated as being the nominal, with the other being informational.

    To answer the original question...

    Just figure one meter = three feet. Close enough, and within the tolerance of any lens distance scale.

    That approximation is only short by 10%, so add 1 foot for every 10 feet.

    The international definition of the inch is exactly 25.4 milimeters.
    Therefore, by extension, if you are measuring in inches, you are still using milimeters. It's only a conversion factor that sets the two apart.

    Even in countries that have supposedly standardized on one system or another, they still use measurements interchangeably. In Canada, you buy gasoline by the liter but you buy milk by the gallon. You might quote the air temperature in degrees Celsius but, when you bake a cake it will be in degrees Fahrenheit.

    We buy milk by the litre. I haven't seen half gallons of milk in Canada for decades. Besides, our gallons were different from yours (4.3L Imperial versus 3.8L US).

    Ovens are still in Fahrenheit, but mostly because American companies are too lazy to make them dual-scale.

    A bunch of Nikons; Feds, Zorkis and a Kiev; Pentax 67-II (inherited from my deceased father-in-law); Bronica SQ-A; and a nice Shen Hao 4x5 field camera with 3 decent lenses that needs to be taken outside more. Oh, and as of mid-2012, one of those bodies we don't talk about here.

    Favourite film: do I need to pick only one?

    Sometimes meters are in feet.


    Well, foot-candles.
    Which always gives me an amusing visual.
    I do use a digital device in my photographic pursuits when necessary.
    When someone rags on me for using film, I use a middle digit, upraised.

    It's the other way round. Inches existed before millimetres. It is the inch which defines the millimetre by stating that 25.4 of them will fit into one inch.
