Well I was bored one night after creating the UnitOfMemory and decided what else could be useful in the future. \u00a0I came up with a UnitOfDistance to convert distances over land. \u00a0Miles v’s kilometers and everything in between. \u00a0The class was easy to come up with, finding the exact conversion rates however was a different story. \u00a0The class works by basing everything on meters. \u00a0A nice conversion method from converting from one measurement type to another.<\/p>\n
If the precision level is not high enough for what you need, simply modify their values in the Enum list to what you do need.<\/p>\n
