+ | ====== Units of Measurement ====== | ||
+ | This article is about my bizarre obsession: units of measurement. | ||
+ | ===== Foreword ===== | ||
+ | Although the contents of this article may give the impression I am in favor of the Imperial system, I assure readers that is not the case. Until fairly recently, I was in favor of the metric system, seeing as I grew up with it. I've never really used Imperial units at all.\\ | ||
+ | However, I believe the metric system has flaws the Imperial system does not. Those are detailed later. Most significantly, | ||
+ | The first half of this article details a suggestion I have for an alternative system, or system// | ||

+ | * This article will use some of the [[wp> | ||
+ | - Specialty | ||
+ | * Units that don't belong in the other two layers. These are used in special circumstances. | ||
+ | I believe this is the most reasonable way to deal with units of measurements.\\ | ||

+ | The local units are vaguely based on the aforementioned Japanese units, but I redefine some. I'll explain those when they come along.\\ | ||
+ | The specialty units are essentially just ones I find neat, nothing deeper there. I have a strange obsession with some of them.\\ | ||

+ | * A unit of depth(([[https:// | ||
+ | * It's a traditional unit, so I see no reason not to include it. Although I'm not sure I'd use it personally. | ||
+ | * Jō (丈) | ||
+ | * 12 尺 or 2 間 | ||
+ | * This is a redefinition. | ||
+ | * I don't remember my exact reasoning for why I wanted to keep this one. But why not eh? | ||
+ | * Nautical Mile (浬/nmi) | ||
+ | * 6112 尺 | ||
+ | * I'm not actually too sure of how it's used in the real world. The most I know is that it's used to define the knot, which is another specialty unit. | ||
+ | * The character used here is apparently the one used for it, although I'm not sure. The alternative form is also 海里(([[https:// | ||
+ | * I have an unusual obsession with the Nautical Mile. | ||
+ | * Lunar Distance (LD) | ||
+ | * 97880 里 or 1, | ||
+ | * I believe it could be used for inter-planetary travel, once that's a thing. The other units of measurement are too big to be useful for that. | ||
+ | * League (lea) | ||
+ | * 3 里 or 108 町 or 6480 間 or 38880 尺 | ||
+ | * I believe it could be used as a unit of depth, similar to the Hiro (尋). | ||
+ | * Gata (型) | ||
+ | * This is just the American inch. | ||
+ | * It's roughly equivalent to the Sun (寸). | ||

+ | ==== Divisibility ==== | ||
+ | The metric system isn't as comfortably divisible as possible. To demonstrate this, let's say there are 1800 yards in a mile, then we compare the divisions of the mile to the divisions of the kilometer. The actual lengths of these units in the real world don't matter. | ||
