Here are a few examples, with possible ways to solve them using Measure.

- How long is a million seconds?
- What's the diagonal?
- How wide is my time zone?
- How far is it from New York to Los Angeles?
- What country has the highest population density?
- How much would I weigh on Mars?
- How big is a 5-acre circle?

`1,000,000 sec`Return (or`1e6 s`Return)- Click Convert (or type Command-K).
- If you wish, check the "Show All" box to see additonal conversions.

`8 inches`Return`2 feet`Return- Click the Equations button (or type Command-=)
- Double-click "Pythagorean theorem, solved for c".

When you double-click the equation, it removes as many values as it needs from the stack & puts the result onto the stack in their place. (The resulting value is marked with a result bar along the left side.)

`Earth`Return- Double-click the value for "Circumference" in the 2nd column.
`24`Return- Click "÷" (divide), or type "
`/`" Return. `this computer`Return- Double-click the "latitude" value in the 2nd column (
*not*the word "latitude" in the first column). - Bring the Stack window to the front (click it, or use Command-1).
- Choose "Cosine" from the Math -> Trig menu.
- Click "x" (multiply).

`cos(latitude of this computer) * circumference of earth/24`Return

`map location of New York city`Return`map location of Los Angeles`Return- Click the "-" (subtract) button, or type "
`-`" Return

- Double-click "countries" in the Contents window. The list of countries contains some columns that aren't needed. Unless you have a very wide monitor, you'll want to remove them, as follows.
- Click in the "area" column, and then choose View > Remove Column "area".
- Click in the "population" column, and then choose View > Remove Column "population".
- View > Add Column > population density.
- If necessary, reverse the direction of the sort, or scroll to the bottom of the list.

`population densities of countries`Return- Click in the "population density" column header (or the comparison column header) to sort.
- If necessary, reverse the direction of the sort, or scroll to the bottom of the list.

- Enter your mass in, say, pounds
^{*}or kilograms, such as`150 pounds`Return. `Mars`Return- Double-click on the "surface gravity" value in the second column.
- Bring the Stack window to the front (click it, or use Command-1).
- Click "x" to multiply.

If you prefer to type more:

`150 pounds * surface gravity of mars`Return

- Double-click "equations" in the Contents window.
- Double-click "area of circle". The equation is displayed in a new window.
- Double-click in the blank Value for the Area variable.
- Type
`5 acres`Return.
