Hi all: Lessons I have learned so far from “Metrication in Australia”. I read some of the PDF after downloading “Metrication in Australia” from http://themetricmaven.com. I noted one difference to the approach towards Metrication page 6 was the avoidance of conversion factors in Education but have

Dear Ms. Neckar, I want to thank you and your copy editor very much for taking the time to a respond to my question about the use of pre-metric units in the article mentioned below. I know how busy you must be in your day-to-day operations to stop and confer about the content of one letter.

An interesting read in how we ended up with the methods we have in the US is Linklater's book "Measuring America". It basically started with Gunter's chain which is still referred to by surveyors even though it essentially is not used anymore.M Moon-- Original Message -- Received: 01:37

The guy who was whinging about thirds, quarters and the duo-decimal system actually has a point – the mathematician Lagrange also considered the situation. Lagrange was on the committee in France that advised the French Revolutionary Government on matters of measurement. In sorting out the m

I suggest visualizing a high school or college track, many of which surround US football fields. The standard sprint race is 100 m, which most folks have actually seen at one time or other--even on TV if not in person. The finish line is often around the middle of the seating area, and the st

I visualize a kilometer as something you can cover by walking during 1/5 of an hour ~10 min (since 5 km/h is the average walking speed), 100 meters is a distance we ran in school, which fit on strait side of the school stadium    Natalie From: Henschel Mark T

Well, I can help you visualize the size of metric units. I think of a hectare as two football fields side by side. (I think of football as a game where the object is to kick a ball into a net. The player who causes a minor foul gets a yellow card and the players who cause major fouls get red

Interesting article on estimating the distance to a thunderstorm: http://www.livescience.com/37734-how-far-away-is-lightning-distance.html   She starts with the usual 5 seconds per mile, but she does include a metric version.  I'm not sure I want to multiply by 340 m/s in my head, however.  It mi
