Re: Conversions

The TI 83 doesn't have unit conversions built in, but they can be programmed. Take a look at for existing programs.

What do you want to convert your calculator to? Or are you asking how to do conversions on a particular make and model calculator?

On the calculator there are conversions of capacity (gallons (US or UK) to liters, liters to gallons (Us), gallons(UK) but there are no conversions from ft^3 to m^3. However you have the basic conversions from in to cm, cm to in, yd to m and m to yd. That is all you need.
To use the calculator to perform a conversion from ft to meters, you enter the number of feet, you press [SHIFT][8] (Conv).
The calculator prompts you to enter a number between 01 and 40. Each number corresponds to a particular conversion. In this case you enter 03
For example convert 3 ft to meters.
Enter 3
Press [SHIFT][8] (Conv)
Prompt: CONVERSION Number 01--40
You enter 03 (ft to m) and press [=]
Calculator displays 3 ft >m, and on the second line 0.9144
Thus 3 ft=0.9144 m
Once you know how to convert one unit of length to another, you get the volume by raising conversion to the 3rd power.
For this to work, you must convert all dimensions to the same unit.

I need to know how to convert 11390cm cubed into metres cubed

Your calculator may or may not have a program for unit conversion, but the best method is to understand the metric system so you can do these conversions without a calculator. A meter is the same as 100 centimeters, so divide 11390 by 100 to get 113.90 m^3.

Rather than relying on a calculator, I highly recommend taking the time to practice metric conversions. It is very common for high school and even college professors to try and trick you by, for example, requesting the answer in centimeters when the question is in meters.

The vatican city is the smallest independent country in the world. it has an area of 47.90 ha. what is the area of the vatican city in in2?

About 742 million.

Not all the conversions are built into the fx-115ES (the list of conversions is printed on the inside of the calculator cover), but here goes.

First, if you don't know it, get the conversion factor from meters to inches. There's no single conversion for this on the calculator, but one way is to convert from 100 cm to inches by pressing
1 SHIFT 02 =
Store this result for future use by pressing

A hectare is 10000 m^2, so 47.90 ha is 479000 m^2. Now convert this to in^2 by multiplying by the square of the stored result. Press
4 7 9 0 0 0 * RCL (-) x^2 =
And you'll see the answer.

My TI-89 won't convert temperatures. It handles other types of conversions fine (like pressure _atm to _mmHg) but gives me a "Error: Inconsistent units" message even with _F to _C or _C to _F. What's...

There is nothing wrong. For all units except temperatures you use the [|=>] the arrow operator to convert from one to anther. For temperature conversions however, you must use the tmpCnv( command.

Exemple of syntax. tmpCnv( is accessed through the catalaog or enter using the Alpha_shifted keys (Ti89)

tmpCnv( 100_ deg C,_ deg F) [ENTER] should give 212
You should explicitly enter the underscores, the degree symbols and the C, and F. The last two need not be capital letters).

Hope it helps.

I would like to know how to work out currency conversion formula on a normal calculator please

rind the exchange rate, perhaps at a site such as:
so, for example, 1 euro is apparently worth 1.4765 US$ at the moment.
if you have 13.82 US$ divide by 1.4765 to get 9.36 euro.
if you had 32.00 euro then multiply by 1.4765 to come up with 47.25 US$

Problem with Casio FX 260 Calculator

Read the screen capture about the MODES of this calculators. DEG,RAD, and GRAD remind the user that the angle units in trigonometric function calculations and coordinate conversions are in degrees, radians or grads. They have nothing to do with the other calculations you are doing.


You can only remove DEG by changing the angle unit to RADians or GRADs. In so doing, the new unit indicator (RAD, GRAD) will be displayed instead. There is no point worrying about the angle unit indicator unless you are performing coordinate conversions or calculating trigonometric functions or the inverse trigonometric functions.

MODE 9 cancels the FIX display format: decimal are displayed with a fixed number of decimal places (set by the user). After this key sequence the decimal display format reverts to NORM(al).
