I want to clearly understand how big 4 cm is in real life. Are there simple examples or household items that measure around 4 cm? This would help students compare metric units accurately.

Four centimeters (4 cm) is a small unit of length equal to 0.04 meters or about 1.57 inches. It is roughly the width of two adult fingers placed side by side or the diameter of a small bottle cap, making it useful for measuring small everyday objects.

The width of two fingers is roughly the thickness of 4.0 cm or 1.57 inches.

A 4-centimeter distance is approximately 1.57 inches which is approximately two fingers of an adult placed next to each other.
