Introduction

One of the basic metric unit to measure the length is a millimetre or mm. At the same time, as we move along the measurement, it goes up to higher metric units like centimetres (cm), metres (m), kilometres (km), and it goes on. So how many millimetres are there in one metre? Since a millimetre is the smallest unit of measuring lengths among the above-mentioned units, one should know its value compared to other higher measuring units.

One Metre Equals How Many Millimetres?

The answer is one metre equals one thousand millimetres. Both metre and millimetre are units to measure the length and distance between objects and places. The relation between 1 millimetre and 1 meter is given as “One meter is equal to 1000 millimetres.”

Mathematically, 1m = 1000mm or 1 mm= 0.001 m

The Conversion From m to mm

To learn the conversion of m to mm, we should know a simple correlation which is 1 m equals 100 cm, and 1 cm equals 10 mm. Thus it makes 1 m equal to 1000mm. And to find a certain value in metres to be converted to millimetres, we simply need to multiply that value of metres by 1000.

Solved Questions

Example 1: Convert 3 m to millimetres.

We know that 1 m = 1000 mm,

\begin{aligned}

&3 m=3 \times 1000 \mathrm{~mm} \\

&3 \mathrm{~m}=3000 \mathrm{~mm}

\end{aligned}

Example 2:

Convert 25 m to mm?

1 m equals 1000 mm

\begin{array}{l}

25\: m= 25\times 1000\: mm\\

25\: m=25000\: mm

\end{array}

Example 3:

Convert 1.2 m to mm.

1 m equals 1000 mm

\begin{array}{l}

1.2\: m= 1.2\times 1000\: mm\\

1.2\: m=1200\: mm

\end{array}
