I use standard and metric almost interchangeably for something's, although for others I will use one or the other almost exclusively.
When dealing with wood and carpentry, I use standard almost exclusively. When doing what work I can on vehicles, I interchange. When driving, I interchange ( it's a must, because the hwy signs are in miles and my speedometer is in kilometers ). When hiking and reading maps for hiking, I use metric almost exclusively, because I know that a meter is a little more than a yard, and a kilometer is a 1000 meters. This way it put's large distances ( anything over 1 kilometer into better perspective ). When dealing with weight, I use, standard. I personally think that kilometers, should be posted on Hwy signs next to miles, that would help most Americans to start to understand some metric, even if on a subliminal level. I have one beef, with metric. There are several very common units ( like millimeter, centimeter, meter, and kilometer ), that are easy to understand, and use. On the other hand, there are also several units, that appear to be ( how shall I say it ) - almost useless and almost a waste of time ( like most of the rest of the units between centimeter and meter, and the units between meter and kilometer ). For an example: I see printed ( and hear people saying ), that something is .5 kilometers from something else - I don't hear that it is 5 hectometers. .95 kilometers, not 95 dekameters ( or decameters - I have found it spelled both ways ). 10 meters, not 1 dekameter ( decameter ) I just don't see the benifet of having what appears to be a units of measure that seams to exists just for the sole reasion to give a level of 10 / 1 or 1 / 10 of the next unit of measure ( up or down ). Just say 1000 m = 1 km and call it good.
