Formula and example

How it is calculated

Converted value = original value × source factor / target factor

Worked example

1.5 V = 1500 mV.

Things to check

  • Prefixes such as milli, micro and kilo scale the volt. A voltage value alone does not determine whether contact is safe.
  • Rounding is applied only to displayed results. Very small or very large values may appear in scientific notation.
