The best unit of measurement for Alex to use for the ropes he is going to use at camp would be centimeters because it is a measurement that fits the needs of his knot shop.
<h3>What is a unit of measure?</h3>
A unit of measure is a unit that is used as a reference and international standard on length, weight, height, among others.
In the case of length, there are several units of measurement such as:
- Kilometres
- Meters
- Miles
- Centimeters
- Millimeters
For a knot-making workshop in a camp, the ideal would be to have a rope of at least 2 or 3 meters. However, the ideal unit of measurement for teaching about knots is centimeters because knots do not require a large amount of rope to tie.
