MEASURE 4 MEASURE
Sites That Do the Work For You - Judy Wolinsky
http://www.wolinskyweb.com/measure.htm
An extensive collection of more than 30 annotated Science/Math
links to interactive sites on the Web that estimate, calculate,
evaluate, translate, etc. Other main topics include Health,
Finance, and Everything Else.
Among many other calculators linked to this page are:
- Countdown! - Objective Consulting Inc. (OCI)
http://www.spiders.com/cgi-bin/countdown/
Calculate the number of seconds between any two events:
find out how long it will be until the millennium, until
your birthday, or simply how long you have been alive.
Answers are also expressed in days, hours, and minutes.
- How Far Is It? - Bali Online
http://www.indo.com/distance/
This service uses data from the U.S. Census and a
supplementary list of cities around the world to find the
latitude and longitude of two places, and then calculates
the distance between them (as the crow flies). It also
provides a map showing the two places, using the Xerox
PARC Map Server, and can supply driving directions.
