A measuring wheel, also known as a surveyor's wheel, is a device used to measure distances. It consists of a wheel with a calibrated circumference attached to a handle or frame. The wheel is rolled along the ground, and the number of revolutions it makes is counted to determine the distance traveled.

Measuring wheels come in different sizes, with larger wheels covering greater distances per revolution than smaller ones. They can be used to measure both straight and curved distances, making them useful for a variety of applications such as surveying, construction, landscaping, and sports field marking.

Some measuring wheels also come equipped with additional features, such as digital readouts, telescoping handles for easy storage and transport, and built-in brakes to help control speed and accuracy. Measuring wheels are a simple and reliable tool for accurately measuring distances over long distances.
