  Two cars related tables released today: Tire codes - speed ratings and Tire codes - load index
2015.07.30
2015.04.06
  This time 3 new calculators for fractions: Fractions: adding and subtracting, Fractions: 4 operations and Fractions: inverse (reciprocal). Each of them shows all sub-steps needed to compute common denominators, create improper fraction (if needed), reduce the fraction etc.

  You love it or you hate it. You understand it or don't have a clue. Percents, percentage is a powerful tool to say about part of something. We made the Percentage calculator to make your life easier.

THIS IS ANCIENT VERSION OF CALCULLA.COM LEFT HERE FOR ARCHIVAL PURPOSES.
ALL CALCULATORS SHOULD STILL WORK, BUT YOU CAN'T BE SURE. WE ALSO DON'T UPDATE THEM, SO EXPECT OUTDATED INFO.
OUR SUGGESTION IS TO MOVE TO RECENT VERSION OF CALCULLA.COM BY CLICKING THE LINK: Binary prefixes
Binary prefixes
Binary prefixes - kibi, mebi, gibi, tebi etc.
Some facts

  • Binary prefixes system is an anolog to metric prefixes (SI), adjusted for the needs of computer science. Binary prefixes differ from related metric prefixes in the following ways:

    • There are no fractional (eg. mili, micro, nano, pico) prefixes, because those have no application in computer science. Smallest piece of information is one bit, which is indivisible.
    • Usage of binary base (number 1024 and its powers), instead of metric one (number 10 and its powers)
  • Despite the existence of binary prefixes, many people still use related SI prefixes, while they're thinking about binary ones. For example someone can say kilo-byte (SI prefix - kilo meaning 1000) bearing in mind 1024 bytes (which is really kebi-byte). Because poeple are rather reluctant to use new prefixes (kebi, mebi etc.), sometimes binary prefixes are called "death law".

Setup table:
Name - Full name of prefix
Symbol - Short prefix symbol
Factor - Equivalent factor
Difference to SI analogue - Difference beetwen SI and binary factor in percent
SI analogue name - Name of related SI prefix
SI analogue symbol - Short symbol of related SI prefix
SI analogue factor - Factor of related SI prefix
