Energy Unit Conversions

As the field of nanophotonics continues to become more interdisciplinary, it is essential to be able to convert between different units of energy by memory. When reading papers, attending talks, having conversations with colleagues, and answering questions in your own presentations, you should always know exactly where a certain measurement lies in the electromagnetic spectrum, regardless of units.

For quick conversions, enter a value into any of the boxes below, and the remaining units will be calculated automatically and rounded to the fifth decimal place. Further below is a table that gives spectral ranges relevant to photonics.
