Q: What is the size of a standard ruler?

A: A ruler is usually 12 inches long. The inch is a standard measurement. A “standard measurement” is a measurement that is used by people to make sure things are measured using the same scale. A long time ago, people used to measure things based on the size of their fingers and feet.

Q: How many inches are in a ruler?

A: One ruler is 12 inches long or 1 foot. Many rulers list the inches on one side but also list centimeters and millimeters on the other side. If your original measurement is 12 inches or below, you can use one of these rulers to measure the same distance in millimeters.

Q: How long is a centimeter on a ruler?

A: Most standard rulers are 30 centimeters long, which makes 1 centimeter equal to one-thirtieth of the length of a standard 12-inch, or 30-centimeter, ruler. The centimeter is a metric unit of measure that, according to Metric-Conversions, is equal to 0.3937 inches.

Q: What side of the ruler is cm?

A: The metric side of the ruler has centimeter numbers from 1 on the far left up to 30 on the far right. The final metric point on the ruler is 30.5, making the ruler 30.5 cm long. The longest lines at each centimeter number indicate the centimeters along the edge of the ruler.
