Here is a comfortable conversion calculator for some typical energy, wavelength and frequency terms, consisting of some the you can find on an SDS.

Additional Info

Energy can be expressed plenty of ways. 2 relationships allow us to easily convert in between energy, wavelength and frequency (see below). If us know any kind of one that these 3 properties, we know the other two.

UnitEquivalent measurements, comments
Wavenumber(cm-1)A wavelength of energy that is likewise called a mutual centimeter. Wavenumbers are obtained when frequency is expressed in Hertz and the speed of light is expressed in cm/s. This unit is generally used in infrared spectroscopy.
Kilojoules every mole(kJ/mol, kJ.mol-1)A Joule, J, is the SI unit the energy and also is characterized as one kg.m2/s2. The prefix "kilo" means 1,000, so one kJ = 1,000 J. As the energies connected with a single molecule or atom are rather small, we often uncover it simpler to talk about the energy uncovered in one mole of the substance, for this reason "per mole". To gain the power for one molecule, divide kJ/mol by Avogadro"s number, 6.022 x 1023.
Kilocalories every mole(kcal/mol, kcal.mol-1)A calorie was originally identified as the lot of energy required to raise the temperature the one gram the water by one degree Celsius. One calorie = 4.184 J. One kcal = 1,000 cal. As soon as we counting calories in ours food, we room actually introduce to kilocalories; e.g. 1 dietary Calorie = 1,000 cal = 1 kcal. Watch the note in the vault entry for information around the mole component of this unit.
NanometernmThe prefix "nano" method 1 x 10-9 = 0.000000001 = 1/1,000,000,000. Therefore, a nanometer refers to power with a wavelength that is 1/1,000,000,000th the a meter. Visible light is do of increase electromagnetic radiation that has actually wavelengths ranging from roughly 300 come 800 nm. For added conversions of nm (as a distance, not energy), view our distance units page.
Hertz(s-1, Hz, /s)A Hertz is a unit of frequency identified as a reciprocal second, s-1. For example, AC present cycles polarity 60 times per second, so we could contact this 60 Hz = 60 s-1. Human being hearing has actually a frequency range from a few hundred Hz up to approximately 20,000 Hz (20 KHz).
Kilohertz(kHz)The prefix "kilo" way 1,000, so there space 1,000 Hz in one kHz. Likewise, there are 1,000 kHz in one MHz.
Megahertz(MHz)The prefix "mega" means 1,000,000, for this reason there space 1,000,000 Hz = 1,000 kHz in one MHz. This is a typical frequency because that radio equipment and high-tech scientific instruments such together magnetic resonance imaging (MRI, or NMR) scanners.
Gigahertz(GHz)The prefix "giga" method 1,000,000,000, for this reason there space 1,000,000,000 Hz = 1,000,000 KHz = 1,000 MHz in one GHz. This is a typical frequency domain because that high speed short-range wireless networks
Terahertz(GTHz)The prefix "tera" means 1,000,000,000,000, so there are 1,000,000,000,000 Hz = 1,000,000,000 KHz = 1,000,000 MHz = 1,000 GHz in one THz. THz scanners have actually recently uncovered use in plane passenger screening devices.
Electron Volt(eV)The electron volt is the energy that us would provide an electron if that were increased by a one volt potential difference. 1 eV = 1.602 x 10-19 J. This hatchet is most frequently used by physicists and electrochemists.
Hartree(Eh or Ha)A hartree (or the Hartree Energy) is the atomic unit that energy and also is characterized as 2R∞hc, wherein R∞ is the Rydberg constant, h is Planck"s consistent c is the speed of light in a vacuum. This is clearly not something you"d find on one SDS.

For the budding scientist: below are the two relationships that relate energy, frequency and wavelength. The an initial is c = νλ where c = the speed of light in vacuum (3.00 x 108 m/s), ν = frequency and also λ is wavelength. The second is E = hν wherein E = energy, h is a special continuous called Planck"s constant (6.63 x 10-34J.s) and also ν is again frequency. The 2nd equation tells united state that frequency is proportional to energy. Combine the two, we find that frequency and energy are inversely proportional to wavelength.

SDS Relevance

Appendix D that OSHA Hazard communication Standard does no specify English or metric units. Therefore, be really careful to note the units as soon as reading numbers such together temperature or push units top top a safety Data Sheet.

If you ever perform a counter or calculation of any type of sort, always remember to compose the units next to each number in her calculation and also make certain that castle cancel properly. NASA once lost a $125 million room probe since of a (failure come convert) unit error! check out the last two links below under additional Reading for an ext on unit conversions.
