Frequently Asked Questions

    The orange equal button allows you to perform multiple calculations. The green button also performs a calculation, but it also dismisses the calculator upon completing the calculation.
  2. Where are your currency rates being pulled from and how often?
    The currency rates are pulled from Google's currency converter once every hour. Please note that Change is not meant as a currency tool for financial trading as the frequency and accuracy of the currency conversion may not be sufficent.
