you read a ruler by conting the little lines first
To use a ruler, place the 0 mark at one end of the object you want to measure. Then, read the measurement at the opposite end where it aligns with the ruler markings. Make sure to use the correct units (inches, centimeters, etc.) as indicated on the ruler.
If you want to measure the length, use a ruler.
To measure in millimeters (mm), use a ruler or measuring tape with markings in millimeters. To measure in centimeters (cm), use a ruler or measuring tape with centimeter markings. For meters (m), use a meter stick or measuring tape with markings in meters. Simply align the start point of the object you are measuring with the zero mark on the ruler or tape and read the measurement at the endpoint.
To use a ruler guide, first align the ruler along the edge of the material you are measuring or drawing on. Ensure that the zero mark of the ruler is positioned at the desired starting point. Hold the ruler steady with one hand while using a pencil or pen to draw or mark along the edge of the ruler for a straight line. For precise measurements, always double-check your alignment and read the markings accurately.

It measures length and distance.It shows the answer in meters, centimeters, or millimeters.
You can measure the length of an object using a ruler, tape measure, or measuring tape.

Make sure to use the appropriate units, such as inches or centimeters.
You look at the markings on its edge.
You use a ruler that is marked with millimetres. Alternatively, you can use a ruler that is marked with inches and then multiply by 25.4 to get the result in millimetres, or use a ruler marked with centimetres and multiply by 10.
