What’s unique about our Calculators?

  1. Calculate With a Different Unit for Each Variable: Now you can calculate the volume of a sphere with radius in inches and height in centimeters, and expect the calculated volume in cubic meters.
  2. Supports a Huge Collection of Measurements and Units: We support 100+ measurements like length, weight, area, acceleration, pressure, speed, time, etc and 1000s of units of measurement.
  3. Widest Coverage of Calculators and Growing: We currently support a huge number of calculators and adding more. Need a new calculator? Just let us know and we shall bring it for you ASAP.
  4. Learn Other Ways to Calculate the Same Output: There maybe more than one way to reach the output. Our generic calculator framework lists them for you. For example an area of a circle can be measured by its radius, diameter, perimeter, area of sector, etc.
  5. Know Other Calculators Using the Same Inputs: Our generic calculator framework identifies other calculators that use the same input. For example, radius can be used to calculate area of circle, perimeter of circle, volume of sphere, etc.
