Calculator usage: horsepower to kilowatts on the Casio fx-991ES PLUS C

Tutoring physics, you face unit conversions. The tutor shows how the Casio fx-991ES PLUS C can be used.

Inside the cover of the Casio fx-991ES PLUS C, at the bottom, is a list of unit conversions. Specifically, it indexes each conversion with a number to which the calculator refers. You’ll see, for instance,

29 hp→kW

which means that 29, entered within the conversion context, performs horsepower to kW.

Example: Using the Casio fx-991ES PLUS C, convert 296 hp to kW.

Solution:

  1. I use COMP mode for this calculation: key in MODE 1
  2. Key in 296 SHIFT 8
  3. The calculator will ask for the conversion number: in this case, key in 29.
  4. Press =

Btw: for kW to hp, it’s 30 instead of 29:)
