Question

Fill in the blanks: 1 kilometre is equal to ---- meters.

Answer 1

Hint: Here a kilometre (symbol: km) is a unit of length in the International System of Units (SI). One kilometre is equivalent to \[0.6214\] miles. To convert km to meters, multiply the km value by \[1000\] or divide by \[0.001\] .

Complete step-by-step answer:
A kilometre term is easy to remember if you keep in mind that the prefix, kilo, is a Greek word that means thousand. Kilometres are usually denoted using the letters \[km\] . So instead of writing the distance to grandma's house is \[2\] kilometres, you can write \[2\;km\] . Kilometres are typically used to measure long distances. If you are looking to figure out the length of a road, the distance between two locations, etc, you would use kilometres.
Hence from the hint, one kilometre is equal to \[1000\] meters.
An example of a kilometre is how far a person will run if a person wants to run for just over \[\dfrac{1}{2}\] of a mile. A unit of length in the metric system equal to \[1000\] meters.
The meter, symbol \[m\] , is the SI unit of length. It is defined by taking the fixed numerical value of the speed of light in vacuum \[c\] to be \[2.99792458 \times {10^8}\;\] when expressed in the unit \[m\;{s^{ - 1}}\] . The SI Unit of mass is kilogram. The kilogram symbol is \[kg\] .
The millimetre (international spelling) or millimetre (American spelling), symbol is \[mm\] . It is a unit of length in the metric system, equal to one thousandth of a metre, which is the SI base unit of length. Therefore, there are one thousand millimetres in a metre.
So, the correct answer is “ \[1000\] meters”.

Note: Note that Opisometers is the instrument most commonly used to measure the lengths of roads, rivers and other line features on maps. Opisometers designed for this purpose provide scales reading the measured distance in kilometres and miles. When we need to get from one place to another, we measure the distance using kilometres. The distance from one city to another or how far a plane travels can be measured using kilometres.
