To translate your calculator, go to http://www.calculatorpro.com. From there you can customize and translate your calculator. The cost for this is either $19.99 per calculator or $9.99 per month for Premium Membership and access to all of the calculators.
Both the plugin and our http://www.calculatorpro.com site let you embed calculators for free that are not customized. We do our best to provide these calculators as cheaply as possible (free if you don't need the customization), but we require the small charge I mentioned for use of our more advanced features.
Let me know if this answers your question!
