Here you
will find a number of pages where you can input data and have
specific quantities calculated for you, for whatever purpose you
have in mind! Virtually all of them are simple
form-entry calculators, but we have also indicated the few that
require JavaScript on your computer.
Astrophysics
Calculator - A neat calculator at the University of Wisconsin
with many built-in astronomical constants. [Java]
USNO Sun and
Moon Calculator - Enter your location on Earth and it
calculates sunrise, sunset etc. [Form]
Distance
between points on Earth - Has nothing to do with the sun, but
its pretty fun to use! [Form]
Cosmology
Calculator - Has nothing to do with the sun, but again its
very useful to us astronomers. [Form]
Sample Size
Calculator - Tells you how big your sample needs to be to get
to a certain level of statistical confidence. Great resource to
apply to data and meaasurements to make sure your answers are
statistically significant [Form].
Radiation Dose and Risk
Calculator - Converts exposure and dosage in Seiverts, Greys,
Roentgens etc, into risks for cancer [Form]
Ohms Law Calculator - Convert currents, voltages, resistences
solving E = I x R [Form]
Earths
magnetic field calculator - Find the strength of Earth's
field anywhere from on the surface into space [Form]
Frequency and Wavelength
Calculator - For electromagnetic radiation. It also gives the
energy of each photon [Form]
Mass to Energy Calculator
- Converts mass to energy using Einstein's Famous Formula
[Form]
Electron
Voltage to Electron Properties Calculator - If you imnput the
energy of the electron in Volts, the calculator tells you it
speed, mass, momentum and DeBroglie wavelength [Form]
Units Converter -
For energy, speed, length, mass etc. [Form]
Magnetic Unit Converter - Converts from one unit into many
others [Form]
Energy and Power
Conversion - Converts Joules and kilowatts into other units
[Form]
