Math Question?

Question

How many meters are in one kilometer? & How many meters are in one decimeter? And if you could please give a source if not thats fine! :)

Answer 1

one kilometer = 1000 meters
one decimeter = 0.1 meter
good luck : )

Answer 2

The metric system works in powers of 10.

By definition, a kilometer is 1000 meters. Also by definition, there are 1/10 meters in one decimeter.

You can see a whole chart on wikipedia. And that's just one source.

It gets trickier if you want to know how many decimeters are in a kilometer. Since you know there are 10 decimeters in a meter (due to the deci-) and that there are 1000 meters in a kilometer (due to the kilo-), you know there are 10,000 decimeters in a kilometer.

The metric system works on the power of 10. You can instantly look at 23 kiloliters and know that it is 2,300,000 centiliters. If you keep the prefixes in mind, then you'll do fine.

The most common prefixes we use are kilo, hecto, deca, deci, centi, and milli.

Thanks to computers, we're seeing a lot more use of mega, giga, and tera. In microbiology, you'll see a lot of micro, nano, and pico.

The extreme prefixes are usually reserved for very specialized fields (such as astronomy or quantum physics).

Answer 3

There are 1000 meters in one Kilometer. There are 10 Decimeters in one meter.

Answer 4

Prefix Symbol Factor Numerically Name
giga G 10^9 1 000 000 000 billion**
mega M 10^6 1 000 000 million
kilo k 10^3 1 000 thousand
centi c 10^-2 0.01 hundredth
milli m 10^-3 0.001 thousandth
micro μ 10^-6 0.000 001 millionth
nano n 10-9 0.000 000 001 billionth**

Thus, for example, one millionth (10^-6) of a meter (m) is one micro meter (μm) or 1 X 10^-6 meters.
