does anybody know about how big is one meter?

One meter has 100 centimeters and 1,000 milimeters. It's a little longer than a yard and almost 40 inches long.

thanks so much

You're very welcome.

Yes, the size of one meter is a well-known and standardized unit of measurement in the International System of Units (SI). A meter is equal to 100 centimeters or approximately 39.37 inches. It is used to measure length or distance.

If you are referring to how to determine the size of one meter without using a measuring tool, you can use everyday objects for estimation. For example, an average-sized adult's stride is approximately one meter. You can measure the distance by taking a step forward and repeating the step until you reach one meter. Additionally, a typical door is usually around 2 meters in height, which can give you a visual reference when trying to estimate the length of one meter.
