What is non standard measurement in math?

Non-standard measurement in math refers to using arbitrary units or informal methods to measure length, volume, weight, or other attributes, rather than relying on established units like meters or liters. Examples include using items such as paperclips, hands, or footsteps as units of measure. This approach is often employed in early education to help students understand the concept of measurement and develop estimation skills. It emphasizes the idea that measurement can be flexible and context-dependent.
