How Many Kilometres is 1 Metre

Introduction

Kilometres and metres both are used to measure distance. And 1 Kilometre=1000 metres. Calculating the amount of something is called Measurement. It is the standard quantity used to express a physical quantity. Measurement can also be defined as the comparison of some unknown quantity with the other known quantity. It includes various concepts such as comparison, conversion, measuring length, time, mass etc. It also includes various other branches such as trigonometry, geometry, AP(Arithmetic Progression), algebra etc.

There are various units in which a given quantity is measured such as for measuring the length of an object, we have a metre, centimetre etc. Similarly for measuring the distance between two cities, we have kilometres, hectometres etc.

Let’s dive into learning various measuring units:

Non-Standard Units of Measurement

These are the units which are used in the early ages of learning. These are the units which measure the given quantity without the use of scales of any kind. One of the ways of measuring the heavier and the lighter object is by using the beam balance. In beam balance or weighing balance, two objects are placed the heavier one is lowered and the other is raised. If both the objects are of equal weight then the weighing balance rests in equilibrium.

Some of the Non - Standard units of Measurement for distance are:

1. Handspan:

• It is the maximum distance between the little finger and the tips of the thumb.

• 8 inches is the general measurement of handspan but it depends on our hand.

2. Footspan:

• The distance between the heel of the foot and the point of the toe is called Footspan.

3. Using rope or a thread is also a way of measuring the length of an object.

Standard Units of Measurement

Those units are predefined and do not change from person to person or country to country. These units are internationally accepted and therefore also called as International System of Units.

Some of the standard units of measurement of fundamental quantities are:

1. Length:

• The standard unit or the internationally accepted unit (SI) for measuring the length is “metre”.

• It's abbreviated as ‘m’.

2. Mass:

• The standard unit or the internationally accepted unit (SI) for measuring the mass is “kilogram”.

• It’s abbreviated as ‘kg’.

3. Time:

• The standard unit or the internationally accepted unit (SI) for measuring the time is “seconds”.

• It's abbreviated as ‘s’.

4. Temperature:

• The standard unit or the internationally accepted unit (SI) for measuring the temperature is “kelvin”.

• It’s abbreviated as ‘K’.

5. Luminous Intensity:

• The standard unit or the internationally accepted unit (SI) for measuring the Luminous Intensity is “candela”.

• It's abbreviated as ‘cd’.

6. Electric Current:

• The standard unit or the internationally accepted unit (SI) for measuring the electric current is “ampere”.

• It’s abbreviated as ‘A’

7. Amount of Substance:

• The standard unit or the internationally accepted unit (SI) for measuring the amount of substance is “moles”.

• It's abbreviated as ‘mol’.

Conversion of Kilometre to Metre

Kilometres and Metres are the Standard units for measuring the distance between two positions. For example, The distance between Manya and Riya is 500 metres or The distance between Delhi and Mumbai is 1365.4 kilometres.

To calculate given kilometres in metres we have the following formula:

\begin{equation}

1 \mathrm{~km}=1000 \mathrm{~m}

\end{equation}

Let’s take some examples for conversion from kilometres to metres:

Example1: 5 km

\begin{aligned}

& 1 k m=1000 m \\

& 5 k m=5 * 1000 m \\

& 5 k m=5000 m

\end{aligned}

Example 2: 12km 500m

\begin{aligned}

& 1 \mathrm{~km}=1000 m \\

& 12 \mathrm{~km} \ 500 \mathrm{~m}=12 * 1000 m+500 \mathrm{~m} \\

& 12 \mathrm{~km} \ 500 \mathrm{~m}=12500 \mathrm{~m}

\end{aligned}

Conversion of Metre to Kilometre

As we had learnt how to convert kilometres to metres, let’s learn how to convert metres to kilometres.

To convert metres to kilometres, we have the following formula:

\begin{equation}

\begin{aligned}

& 1000 m=1 k m \\

& 1 m=(1 / 1000) k m \\

& 1 m=0.001 km

\end{aligned}

\end{equation}

So we understood that the direct formula from metres to kilometres conversion is:

1 \mathrm{~m}=0.001 \mathrm{~km}

Let’s take some examples of conversion from metres to kilometres:

Example1: 12500 metres

\begin{equation}

\begin{aligned}

& 12500m =12500*0.001km \\

& 12500m = 12.500km

\end{aligned}

\end{equation}

Example2: 12 metres

\begin{equation}

\begin{aligned}

& 12m =12*0.001km \\

& 12m = 0.012km

\end{aligned}

\end{equation}

Conclusion

Following points we had learnt:

• Measurement is the way to measure the amount of something.

• There are two types of measuring units i.e Standard units and Non-Standered units.

• Standard units are the one which is internationally accepted and does not changes.

• Non-Standered units are the one which is used in the early years and is different for different persons.

• There are 1000 metres in 1 kilometre.

• There are 0.001 kilometres in 1 metre.
