Use the upper multiplication factor to convert from a left-side quantity to the corresponding right-side quantity.
Use the lower multiplication factor to convert from a right-side quantity to the corresponding left-side quantity.
I have included some of the more common conversions used in hydrology and meteorology and have forgone some of the more elementary ones (such as feet to inches or meters to centimeters). The conversion factors shown have been rounded to no more than 4 significant digits;however, the full precision (as supported by your computer) is used in calculations.
These instant conversions use JavaScript, which requires a browser newer than Netscape 2.0 or Internet Explorer 2.0. If you don't have one of these browsers, you can still use the conversion factors, but you'll have to do the math yourself.
