Notes on usage

If you select an input value and read its equivalence, then change the number of significant figures, the number of figures displayed will not change until you make a change in the input quantity or the equivalence units. After you make the change in the input quantity, you also have to click on the equivalence-value window. The change in the input can be as little as appending a zero to a decimal fraction or appending a decimal point to an integer.

If with a given significance the equivalence value rounds off so as to have one or more trailing zeroes, it will seem as if not enough significant figures are being displayed. For example, with five significant figures set, '1.1690' will display as '1.169'. This is apparently one of the things you get when you get JavaScript.

It's possible to enter more figures than the input window will hold, in which case the display scrolls to the left as it accepts more figures. The number the window will accept before it scrolls varies a little from one browser to another. If the window appears to be full, it's a good idea to press 'Home' before you believe the value displayed. Pressing 'Home' will ensure that you see the most significant figures of the value. Also, pressing 'End' will ensure that you see the least significant figures.

The equivalence window will also scroll, so the same caution applies there.

History

Bill Taylor adapted a JavaScript from [a source whose URL no longer works - 2005 Jan 11].
In his words "I added the script for temperature conversion and the table structure to make it line up left to right".

I, Bob Cunningham, (on 5 July 1999) made changes in Bill Taylor's version to do the following:
