Small distance or height is measured in millimeter. Larger quantities are measured in kilometers.
Millimeters are typically used for very small distances, such as the thickness of paper or small electronic components. Kilometers are used for much larger distances, like the length of a road or the distance between cities.
Long distances are typically not measured in millimeters because such small units would be impractical for expressing vast measurements. For example, distances like those between cities, countries, or celestial bodies would yield unmanageably large numbers in millimeters, making them difficult to comprehend and use. Instead, larger units like kilometers or miles provide a more convenient and understandable framework for these measurements.
Millimeters are ideal for measuring small distances where precision is crucial, such as in engineering, manufacturing, and craftwork. They are commonly used for dimensions of mechanical components, electronic parts, and in fields like woodworking or jewelry making, where fine details matter. Additionally, millimeters are useful in medical contexts, such as measuring anatomical structures or in imaging. Overall, any application requiring high accuracy in small-scale measurements would benefit from using millimeters.
The Isle of Man is a landmass, so its area would typically be measured in square units such as square kilometers (km²) or square miles (mi²). When discussing distances on the Isle of Man, lengths would be measured in linear units such as meters (m) or kilometers (km) for shorter distances, and potentially nautical miles (nmi) for longer distances along its coastline.
Distances on the road, or very large parcels of land. Probably the distance from the earth to the moon.

Take the actually measurements in kilometers (km) and convert them to centimeters (cm) and record them so that the measurements will be more accurate.

I would use meters because well thats the only other choice to choose from!
Kilometers
The decision when to use kilometers and when to use meters is sort of arbitrary. But usually you would use kilometers when you expect the distance to be close to a kilometer, or larger than a kilometer. For example, distances between towns or cities are often expressed in kilometers.
You would typically measure the distance around a school in meters, as this is a more precise unit of measurement for shorter distances. Kilometers are better suited for measuring longer distances.
You should use whichever measurements your characters would use!
