# Some facts#

- The mass is a measure of
**the amount of substance**. - The mass conception is closely related to the concept
**of inertia**. This is a feature of material objects, which basically means that the body once set in motion retains its speed as long as it will not work on any external forces. - The mass of body also determines the
**gravitation force**. Any two bodies interact with force directly proportional to the product of their masses. - There are objects without mass for example
**photons**. - In the first half of the twentieth century, Einstein created theory saying there is
**equivalence of mass and energy**. This theory is related to one of the most famous physical formulas:**E = mc**. The theory has been confirmed experimentally and succesfully applied to create^{2}**nucler power plant**and**nuclear weapon**. In both cases the energy is "created", while loss of mass is noticed. In other words, the mass is converted into energy.

# How to convert#

**Enter the number to field "value"**- enter the NUMBER only, no other words, symbols or unit names. You can use dot (**.**) or comma (**,**) to enter fractions.

Examples:- 1000000
- 123,23
- 999.99999

**Find and select your starting unit in field "unit"**. Some unit calculators have huge number of different units to select from - it's just how complicated our world is...**And... you got the result**in the table below. You'll find several results for many different units - we show you all results we know at once. Just find the one you're looking for.
