Often we use different constants such as Plank Constant ( h = 6.63*10-34 Js ), Mass of Electron ( me=9.11*10-31 kg) etc in calculation. It is difficult to keep in mind such values all the time. Calculator has kept stored such constant values in it's memory.
Example: What are the values of Plank Constant and Charge of an Electron ?(Ans: h=6.63*10-34 Js and e=1.6*10-19 C )
Solution:
(Plank Constant)
CONST >> 0 >> 6 >> =
(Charge of an Electron)
CONST >> 2 >> 3 >> =
In the back cover of calculator there is a list of constant from 01-40.
To convert from one unit to another (such as atm->Pa ) with calculator is very easy.
Example: Convert 36 km/h into m/s. ( Ans:10 m/s)
Solution:
3 >> 6 >> SHIFT >> CONST >> 1 >> 9 >> =
In the back cover of calculator there is also a list of conversion from 01-40.
