Why VoltConvert exists
Most online converters hand you a number and ask for blind trust. VoltConvert was built on the opposite idea: every calculator shows the formula it used, a worked example, and a reference table — so an electrician sizing a 240 V circuit in Ohio, an engineering student in Manchester, or a homeowner sizing a storm generator can verify the result, not just copy it. All conversions follow standard SI and electrical-engineering definitions (the same IEC and NEC conventions your code book uses), they run entirely in your browser, and they're free with no signup.
