One day, i took my laptop computer to work in the coffee shop, just had a project on hand, and i had to tell the customer the actual size of a product. Just like usual, i didn’t carry a ruler with me, so i connected to the internet and tried to find an online virtual ruler to measure my product.

Unfortunately, after i tried the virtual online rulers on the Internet, i found a problem that these existing online rules are not very accurate. If i just want to know what the approximate length is, that’s fine, but what i need is a more precise length so that i can apply it to my daily work.

So later, we developed an online ruler by ourselves. It not only improves the accuracy of the measurement, but also has a scale of inches and centimeters so that it can be used in our work.

If you are like us, you need a precise online ruler to measure the product size, i believe this online virtual ruler can also meet your needs.

Clicking on the ruler will mark a red vertical line for easy comparison of metric and imperial lengths.

I am very happy that many people like our online ruler,
also i am very excited to review all the comments from all the visitors.
Regarding the joke about comments or commands here,
i decided to add a new “command” function(on the page top) for our dear friends,

In addirion to showing the length, I also addewd a comparison command, I try to make the AI interaction smarter, hope you like our new command function 😛, welcome to try it and share it, let me know your idea.

This ruler measure in two different units of length, inches on one side (English ruler) and centimeters on the other side (metric ruler). A metric ruler is use to measure centimeter(cm) and millimeter(mm), the centimeter is a unit of length in the International System of Units; An English ruler provides incremental measurements in inches, with each inch further divided into smaller fractions.

Read an English ruler using fractions of an inch. The distance between any two large numbered lines is 1 inch. The large unnumbered line that is halfway between them is 1/2 inch. The smaller (but still prominent) line between the 1/2 mark and the numbered inch line is 1/4 inch. The tiny little lines between all of the more prominent lines are 1/16 inch.

Observe the much simpler metric rulers. The distance between any two large numbered lines is 1 cm, a metric ruler features two types of lines. The largest mark centimeters, or cm. The smallest lines mark millimeters, or mm. The prominent line between any two numbered lines is 1/2 cm. The small lines between the 1/2 mark and the numbered centimeter mark are 1/10 cm, otherwise known as a millimeter, keep in mind that there are 10 mm to 1 cm. The measurements are decimalized and there are no fractions.

Record distances by the name of the line that it most closely matches. If the length of an object goes to one mark past the halfway mark on your ruler then it will be 9/16 inch on an English ruler or 6/10 cm (or 6 mm) on a metric ruler.
