Every centimetre is marked with an even longer line and a numeric label. Every 10th centimetre is usually predominantly marked. They might be referred to as yardsticks, metre-sticks or "inch sticks". In the United States, the marking is usually in customary units (three feet 3 + 3 ⁄ 8 inches with inch and fractional inch). Hybrid measures ...

The metre (or meter in US spelling; symbol: m) is the base unit of length in the International System of Units (SI). Since 2019, the metre has been defined as the length of the path travelled by light in vacuum during a time interval of 1 / 299 792 458 of a second, where the second is defined by a hyperfine transition frequency of caesium.
Diagram showing the path of a driver performing a U-turn.A vehicle with a smaller turning diameter will be able to perform a sharper U-turn. The turning radius (alternatively, turning diameter or turning circle) of a vehicle defines the minimum dimension (typically the radius or diameter) of available space required for that vehicle to make a semi-circular U-turn without skidding.
