You can use several different constants in your mathematical expressions.
Note: When you enter constants multiplied by a number, make sure to indicate the multiplication explicitly. For example, enter
2*c instead of
2c, and enter
|C||The speed of light in m/s (2.998^8)|
|e||Euler’s number (2.718…)|
|g||Gravity (9.80 m/s^2)|
|i||The square root of -1|
|j||The square root of -1|
|k||The Boltzmann constant (~1.38^-23 in Joules/Kelvin)|
|pi||The ratio of a circle’s circumference to its diameter (3.14159…)|
|q||The fundamental charge (~1.602^-19 Coloumbs)|
|T||The positive difference between 0K and 0°C (273.15)|
