![]() I would recommend getting use to them, from what a lot of my textbooks (and they are very recent ones too) tell me, is that the US is very slowly starting to go into using the Metric system (hell, a lot of parts on newer American cars are now starting to be produced in Metric), so it could be useful knowing some of these. Granted, both are right, but Pascals are much more universally accepted. You can also get yourself a small table with conversions (one you can print out) (though for this, you should be more or less concerned with length, so knowing the conversions for those are pretty simple.) Of course, you can also convert units using Google (type in like 3ft in cm, and it gives you the answer right away), I sometimes use it when I myself don't feel like having to fill in these conversion factors (like in my Flight Structures Book, pressure and stress is usually measured in Pascals (Pa), but for some reason when I look at the answers for my work, the book provides them in Newtons per millimeter squared (N/(mm^2)). I guess it could be a good start for you anyways, especially for your later science based cl***** and if you're going into a tech based major such as Engineering (a few problems can be done in one system, but require answers in another, like in my Aero 1 class, where we might have problems that are completely in English system, but have to be done in Metric/SI.) It is simply a lot like I illustrated in my above post. I am just in the 9th grade and I don't know much about conversions but I guess I can learn now.Īs said though, it isn't a very hard concept at all, if you can do the 4 basic functions (add, subtract, divide and multiply) you can easily do this. So get the dimensions you need of the real thing, divided by the scale (like if I were doing a 5000 cm long wall in 1:400, I'd just calculate (5000 cm / 400) and should end up with a scaled down version of this wall (which in 1:400 should be 12.5 cm). Remember, you multiply the numerators and divide the denominators.ġ5ft=(12in/1ft) (here ft. Click the 'inch' button to display the real-world size of 240 inches (20 foot). Here is how that would work out (mind you, I do have certain limitations of how to display it, but it should be easy to show). This calculator does the reverse of the one above and converts from Scale Size to Real Size. ![]() Then you know that 1in is 2.54cm, so then you multiply by 2.54 cm and vola, you're already in metric! In my opinion, it's better to convert your original structure to metric then scale it down. You got 15 ft, well you know that 1 ft is 12 inches, so you multiply this by 12 in. Just remember the conversion factors you learned in your cl***** (likely Chemistry, that's where I got introduced). ![]() Yeah, working in metric (where everything is based on a series of 10) is so much easier in these scales than in the US system (where everything is based off of some irrational number, like 1/16). ![]()
