Engineer's Toolkit is a useful utility that includes 21 different tools, 11 of which deal with conversions

Engineer's Toolkit was initially designed to help high school students cut time doing homework.

Engineer's Toolkit later expanded in capabilities and became a full blown collection of Physics, Chemistry, and Mathematics tools to help engineers, teachers, and students all over the world in production, college, and high school environments.

Engineer's Toolkit is a useful utility that includes 21 different tools, 11 of which deal with conversions.

Here are some key features of "Engineer s Toolkit":

· Calculator - provides basic and advanced calculations, goes beyond your basic addition, subtraction, multiplication, division functions. Includes powers, trig functions, factorials, logs, ceiling, floor, modulus functions and many others.
· Geometry Line Functions - this function tool lets you calculate slope of the line and the distance between the two points with a click of a button.
· Pythagorean Theorem - solves for hypotenuse or any of the sides of a triangle based on any known information provided.
· Quadratic Formula - solves a quadratic equation by finding it's roots.
· Permutation/Combination - finds permutations and combinations.
· Absolute Uncertainty - finds absolute uncertainty and percent of absolute uncertainty for a given input.
· Bend Allowance - finds bend allowance for mechanical engineering calculations.
· Solar System Planets - provides various data for the planets in solar system, such as distance from the sun, radius, mass, etc.
· SI Prefixes - converts powers of 10 into prefixes and their abbreviations, for example, 10^18 = exa (E).
