Unit conversion utility
Introduction
The TrueGeometry app now has utility section in it. The very first functionality added is the unit conversion. It has about 21 measurments that can be used for conversion. The app further also has following utilities:
- Unit Conversion,
- Density (Solid, Fluid e.t.c),
- Volume Calculator (Various daily purpose tank shapes),
- Speedometer with risk calculation,
- Gear ratio calculations,
- Belt & Pully,
- Automobile Engineering (Internal Combution Engine utils, Mass Moment Of Inertia),
- Civil Engineering (Beams Deflection and Moment Of Inertia),
- Tank Volume Calculator,
Unit conversion is a process with multiple steps that involves multiplication or division by a numerical factor or, particularly a conversion factor. The process may also require selection of the correct number of significant digits, and rounding. Different units of conversion are used to measure different parameters.

or the pro version
Unit Conversion Scope
Section below define the various measurement classes.
Amount of substance (moles, millimoles, etc.)
The amount of substance, symbol n, of a system is a measure of the number of specified elementary entities. An elementary entity may be an atom, a molecule, an ion, an electron, any other particle or specified group of particles.
Angles (degree, radians, etc.)
An angle is formed when two rays are joined together at a common point. The common point here is called node or vertex and the two rays are called arms of the angle. The angle is represented by the symbol ‘∠’. The word angle came from the Latin word “Angulus”.
Area (hectares, acres, etc.)
Area is defined as the total space taken up by a flat (2-D) surface or shape of an object. The space enclosed by the boundary of a plane figure is called its area. The area of a figure is the number of unit squares that cover the surface of a closed figure.
Digital data (byte, gigabit, etc.)
Digital data, in information theory and information systems, is information represented as a string of discrete symbols, each of which can take on one of only a finite number of values from some alphabet, such as letters or digits.
Density (grams per liter, micrograms per milliliter, etc.)
Density is the measurement of how tightly a material is packed together. It is defined as the mass per unit volume. Density Symbol: D or ρ Density Formula: ρ = m/V, where ρ is the density, m is the mass of the object and V is the volume of the object.
Energy (Joule, kilowatt-hour, etc.)
Scientists define energy as the ability to do work. Modern civilization is possible because people have learned how to change energy from one form to another and then use it to do work.
Force (Newton, kilogram-force, etc.)
In Physics, force is defined as: The push or pull on an object with mass causes it to change its velocity. Force is an external agent capable of changing a body’s state of rest or motion. It has a magnitude and a direction.
Fuel consumption (miles per hour, kilometers per hour, etc.)
Fuel consumption is a measure of how efficiently a vehicle uses up fuel, comparable to fuel economy (or fuel efficiency). Fuel economy quantifies a car’s efficiency by how far a vehicle travels using a particular amount of fuel, i.e., in miles per gallon (MPG) or kilometers per liter (kmpl).
Length (meter, miles, etc)
Length is defined as the measurement or extent of something from end to end. In other words, it is the larger of the two or the highest of three dimensions of geometrical shapes or objects. For example, a rectangle has its dimensions as length and breadth.
Molar mass (grams per mole, milligrams per millimole, etc.)
Molar mass M is the mass of a chemical compound divided by its amount-of-substance measured in moles. It is defined as MB = m/nB, where m is the total mass of a sample of pure substance and nB is the amount of substance B given in moles.
Mass (kilograms, ounces, etc.)
Mass can be experimentally defined as a measure of the body’s inertia, meaning the resistance to acceleration (change of velocity) when a net force is applied.
Numeral systems (hexadecimal, binary, etc.)
A numeral system is a writing system for expressing numbers; that is, a mathematical notation for representing numbers of a given set, using digits or other symbols in a consistent manner.
Power (kilowatt, horse power, etc.)
In physics, power is the amount of energy transferred or converted per unit time. In the International System of Units, the unit of power is the watt, equal to one joule per second. In older works, power is sometimes called activity. Power is a scalar quantity.
Pressure (bar, psi, etc.)
Pressure is defined as the physical force exerted on an object. The force applied is perpendicular to the surface of objects per unit area. The basic formula for pressure is F/A (Force per unit area). Unit of pressure is Pascals (Pa). Types of Pressures are Absolute, Atmospheric, Differential, and Gauge Pressure.
Shoe size (eu size, us size, etc.)
There are a number of different shoe-size systems used worldwide. While all shoe sizes use a number to indicate the length of the shoe, they differ in exactly what they measure, what unit of measurement they use, and where the size 0 (or 1) is positioned. Some systems also indicate the shoe width, sometimes also as a number, but in many cases by one or more letters. Some regions use different shoe-size systems for different types of shoes (e.g. men’s, women’s, children’s, sport, and safety shoes). This article sets out several complexities in the definition of shoe sizes. In practice, shoes are often tried on for both size and fit before they are purchased.
SI prefixes (giga, tera, etc.)
Eight original SI prefixes were officially adopted: deca, hecto, kilo, myria, deci, centi, milli, and myrio, derived from Greek and Latin numbers. Initially, all prefixes were represented by lowercase symbols. The first General Conference on Weights and Measures (CGPM) approves the 8 prefixes for use.
Speed (miles per hour, kilometers per hour, etc.)
In everyday use and in kinematics, the speed (commonly referred to as v) of an object is the magnitude of the change of its position over time or the magnitude of the change of its position per unit of time; it is thus a scalar quantity
Temperature (celsius, fahreneit, etc.)
Temperature is the degree of hotness or coldness of an object.
Time (seconds, years, etc.)
Physicists define time as the progression of events from the past to the present into the future. Time value only moves in one direction.
Torque (newtons per meter, dyne meter, etc.)
Torque is a measure of the force that can cause an object to rotate about an axis. Just as force is what causes an object to accelerate in linear kinematics, torque is what causes an object to acquire angular acceleration.
Volume (liter, cubic meters, etc.)
Volume is defined as the space occupied within the boundaries of an object in three-dimensional space. It is also known as the capacity of the object.
