Density of SubstanceĮnter the known density of the material being measured. The formula used by this calculator to determine volume from mass and density is:Įnter the measured mass of the object and select the appropriate mass measuring units. This calculator will determine the volume of a quantity of substance from the measured mass and known density and display a conversion scale for variations in each parameter.įor example this tool can be used to calculate the amount of storage volume required for a given quantity of substance mass.

Determine density from mass and volume measurements When studying chemistry you will measure many quantities with units that are actually combinations of the base units.

I'll explain the concept of unit conversion and do multiple examples explaining. P ( mW) = 1.989 × 10 -10 × F/ l (nm) (equation 5)įor any given flux and wavelength (in nm), equation 5 can be used to calculate the corresponding average power (in mW). If unit conversion has never made sense to you then please watch this video. Average power is related to flux and photon energy by: The power of short wavelength light sources in the EUV to X-ray range are often expressed as photon flux ( F) in the units of photons per second (ph/s). To convert from g into units in the left column divide by the value in the right column or, multiply by the reciprocal, 1/x. medical software, clinical software, medical systems, medical calculators, clinical calculators, medical information processing, practice guidelines. Power (P) is the rate of energy transfer with the SI unit of 1 Watt = 1 J/s. Thus, equation 1 above can be rewritten for photon energy in eV and wavelength in nm as: The International System of Quantities (SI) have defined 1 eV to the exact value of 1.602 176 634 ×10 −19 J.

Next, select the starting unit and enter a value in the FROM input. Acceleration Many different acceleration constants.

Be aware of the units supported by the Pressure Conversions Calculator by going ahead. Online Conversion is a resource for weights, measures, calculators, converters. Just input the data in the input fields and choose the output unit you want to convert from the list available next to the input field. To make chemistry unit conversions, first choose the chemical in the top pull-down selector. Make the most out of this online tool and change from one unit of Pressure to another unit in a split second. SI units: Système Internationale dUnités US units: Gravimetric, imperial, or traditional English units. For short wavelength sources in the EUV to X-ray range, researchers often discuss photon energies in units of eV (or keV for hard X-rays) out of convenience. In this calculator, mcg is the abbreviation for micrograms. Photon energy can be expressed using any unit of energy such as the electronvolt (eV) or the Joule (J). Where h is Planck's constant (6.6261 x 10 -34 J*s) and c is the speed of light (2.9979 x 10 8 m/s). The energy of light (or photon energy), E, is inversely proportional to the wavelength by the equation: Calculation Theory Photon Energy and Wavelength 1 in 2.54 cm 0.0254 m: 1 ft 30.48 cm 0.3048 m: 1 yard 91.44 cm 0.9144 m: 1 mile 1.6093 Km 1609.3 m. An online unit conversion calculator for metric/imperial units that allows you to convert between several units of measurements like length, weight, area.
