Calculator usage: the ENG feature on the Casio fx-991ES PLUS C
Tutoring math, calculator features are always topical. The tutor mentions the ENG function on the Casio fx-991ES PLUS C.
Back in my Halloween, 2015 post, I explain the general idea of the ENG function – that engineers and technicians often like to refer to measurements in “thousand” groupings. For instance, 1249W is 1.249kW; 0.067A is 67mA.
Example: convert 0.78A to mA
- Key 0.78 = (you must press = for this to work)
- Press ENG: hopefully you see 780×10-3
Example: convert 1249W to kW.
Solution: to go up to the bigger unit, use SHIFT ENG, like so:
- Key 1249 = (once again, you must press =)
- Press SHIFT then ENG. Hopefully you see 1.249×103
