Calculatoredge: when one calculator isn't enough
Calculator choices from Calculatoredge.
One of the more useful tools in an engineer's toolbox is a physical calculator. Why does it seem to get lost when it's truly needed? Workstations usually save the day. Those included in your OS of choice (Windows, iOS, Linux, etc.) are good for simple tasks but not so great for other things, even in scientific mode.
Searching for the right one online will net you roughly 131 million choices. Which one are you to choose when there are so many? Why not choose them all?
Almost all calculator versions known to humankind are located in one convenient site, Calculatoredge. It boasts no fewer than a few hundred calculators for just about every field imaginable (and perhaps some that are unimaginable), including electrical, mechanical, civil, chemical, and even math. There's no need to search aimlessly for that obscure number cruncher ever again. Some of the more complex calculators even come with some rudimentary instructions.
