What is 1km equal to?

1km = 1000m. Kilo (from the Greek χίλιοι, literally a thousand) is a decimal unit prefix in the metric system denoting multiplication by one thousand. It has been used in the International System of Units where it has the unit symbol k, in lower case.

Centi- (symbol c) is a unit prefix in the metric system denoting a factor of one hundredth. Proposed in 1793 and adopted in 1795, the prefix comes from the Latin centum, meaning "hundred". So there are 100,000 cm in 1 km

Milli- (symbol m) is a unit prefix in the metric system denoting a factor of one thousandth Proposed in 1793 and adopted in 1795, the prefix comes from the Latin mille, meaning "one thousand". So there are 1000,000 mm in 1 km

It IS an easy question, if you learned the metric system in school. I did get it right, but it was hard, because when I went to school, we were still learning feet and yards.

A good trivia question … not everyone is at the same educational level, questions like this are good to have … well done.

Lynne Zeman

Has nothing to do with educational level or pot. Kilo = thousand. Basic.

I live in a country that uses the metric system, like most of the world. However, even if you don’t, most people know that kilo = thousand so together with metre it must be 1000m.

smitch, I just learnt something new, thanks

the metre is the baseline ... anything larger is in Greek: deca, hecto, kilo (times 10,100,1000) and anything smaller is in Latin: milli, centi, deci (1000th, 100th, 10th) not difficult to understand. That's the way it's taught in France !

As a science major, the metric system is used exclusively. The US or Imperial Systems are not used in Science.

Got it right!

Diane Lynn Kinsman

Learned it, still prefer not using it.. used to do estimates, switched it back to feet and inches, learned to use both in school..odd my son learned metric only ... needed to know both for work, he goes back and forth with it so easy.

Simple, even though the Brit spelling is used - "metre"

karen twirly

Got it.

Anita Clark Morton, Ah ! School... Farmer Jones wants to build a barn 50 Ft Wide, 15 Meters Long, and 10 Yards High. How many Sq Ft of wood will he need ? My first thought was that Farmer Jones had best stick to farming and leave Carpentry to one whom uses just one Tape Measure...! An aside: I could not accept the fact that something like : a -( z + sq root of n) was any kind of an answer !

jack patti go

Anita Clark Morton, all countries should be using the metric system; it’s much easier to calculate. But it was difficult when we switched. Took a while!
