Arrim ONE play online

Arrim ONE can be used to measure the dimensions of straight lines, circles, angles and curves. It is also a leveling and dividing tool.

Arrim ONE supports both Imperial & Metric Unit System. You can measure in ft, inch, yard, mm, cm, and m. And you can also choose the maximum precision.

In some cases, ARRIM ONE can achieve the level of precision which is impossible for other tools. For example, if you want to measure the radius of a circle, because you are not sure where the circle centre is, the measurement with other tools may lead to a large deviation. ARRIM ONE can easily solve the problem with an algorithm based on the principle of three points defining a circle.
