All online calculators

  • Barometric leveling
  • Base 64 encoding and decoding

    The calculators encode string to base64 string and decode back to original string. Special characters (+/) , generally produced by base64 algorithm, can be replaced by the data provided in additional parameter.

  • Bayes’ theorem

    This online calculator calculates posterior probabilities according to Bayes’ theorem.

  • Beaufort scale

    Conversion between wind speed measurement units including Beaufort numbers, km/h, m/s, mph, fps.

  • Bernoulli trials table

    This online calculator calculates probability of k success outcomes in n Bernoulli trials with given success event probability for each k from zero to n.
