Length & Width:
* Wingspan: This is the distance between the wingtips. It's usually measured in meters.
* Length: This is the overall length of the plane, from nose to tail. It's also usually measured in meters.
Height:
* Height: This is the vertical distance from the ground to the top of the plane. It's measured in meters.
Area:
* Wing area: This is the area of the wing surface. It's measured in square meters.
* Total surface area: This is the total area of the plane's skin. It's measured in square meters.
Other measurements:
* Weight: Measured in kilograms or metric tons.
* Fuel capacity: Measured in liters.
Millimeters are rarely used for measuring planes. They are too small a unit for measuring large objects like aircraft. However, you might encounter millimeters when discussing specific components, like the thickness of a piece of metal or the diameter of a bolt.
Important Note: The specific measurements of a plane vary greatly depending on the model and its purpose. There are tiny, private planes and massive, commercial airliners.
