Length measurements in the metric system

The length was the first quantity affected by the metrication process at the peak of the Enlightenment period in France. The meter was adopted as the base unit for length. From this human-scale measurement unit, simple divisions and multiplications by 1010 and its powers provided us with many units suitable for every possible usage.

The kilometer is one of these derived units: it takes its name from the meter and the Greek word for thousand. While the meter is perfectly suitable to measure people or objects, we can manipulate it with little effort; the kilometer measures the distance between cities. Since on scales much larger than the dimensions of a moderately-sized country, our brains start to miss the true meaning of length; we also specify planetary-scale distances and interplanetary distances with the kilometer simply by attaching the units to large numbers (have you ever wondered why a million kilometers sounds more fitting than a billion meters?).

Let's learn how to convert kilometers to meters and vice-versa!

How to convert kilometers to meters: formula and conversion factor

The conversion between km and m is straightforward, thanks to the regularity of the metric system. A kilometer corresponds to a thousand meters. We can write this conversion in this form:

1 km=1, ⁣000 m1\ \mathrm{km} = 1,\!000\ \mathrm{m}

where we can see the origin of the prefix kilo-, or, to highlight even more the power of the metric system, use the scientific notation:

1 km=103 m1\ \mathrm{km} = 10^3\ \mathrm{m}

here we see how meters and kilometers are three orders of magnitude away from each other. Between them we can find the decameter (101 m10^1\ \mathrm{m}) and the hectometer (102 m10^2\ \mathrm{m}), two metric yet not commonly used units.

Convert from km to m

If you have a measure in kilometers and you want to convert kilometers to meters, simply multiply by 10001000. If you're going to perform the opposite operation, divide the measure in meters by 10001000.

To remember which one to use, remember that the meter is much smaller than the kilometer; hence when performing the conversion from kilometers to meters, you should expect the magnitude of your measure to increase (multiplication by 10001000).

Example of km to m conversion

Take the distance between the White House and the U.S. Capitol in kilometers: d=2.525  kmd = 2.525\ \mathrm\ \mathrm{km}. Let's bring it down to a larger number that is more representative, for example, of the number of steps you need to take to move from one monument to the other.

Apply the formula to convert from kilometers to meters:

2.525 km2.525 km×1, ⁣000 m/km=2, ⁣525 m\begin{split} 2.525\ \mathrm{km}&\equiv 2.525\ \mathrm{km} \\ &\times1,\!000\ \mathrm{m/km} \\ &= 2,\!525\ \mathrm{m} \end{split}

That's it! Easy as pie.

How do I convert from kilometers to meters?

To convert from kilometers to meters, follow two simple steps:

  1. Measure the desired length in kilometers: you can do it on mapping software or maps or simply walk and count your strides.
  2. Convert the measure in kilometers to meters by multiplying it by 1000.

You are all done: if your measure in kilometers has decimal digits, move the separator three positions to the right!

How much is 3.5 km in meters?

3.5 km equals 3,500 m. To find this result, apply the formula to convert kilometers to meters:
3.5 km ≡ 3.5 km × 1,000 m/km = 3,500 m
The magnitude of your measure increased; a meter is a smaller measurement unit than a kilometer. Hence you can fit more in the same length.

Is 1000 m equal to 1 km?

Yes: 1,000 meters are equal to 1 kilometer. This equivalence is rooted in the regularity of the metric system: the prefix kilo- stands for a thousand, and prepending it to the base unit (the meter, in our case), corresponds to multiplying the units a thousand times.
