A cable length or length of cable is a nautical unit of measure equal to one tenth of a nautical mile or approximately 100 fathoms. The unit is named after the length of a ship's anchor cable in the Age of Sail. The definition varies:
| 1 cable length (imperial) ≈ 555955.2 french; charriere | 4 cable length (imperial) ≈ 2223820.8 french; charriere |
| 1.5 cable length (imperial) ≈ 833932.8 french; charriere | 4.5 cable length (imperial) ≈ 2501798.4 french; charriere |
| 2 cable length (imperial) ≈ 1111910.4 french; charriere | 5 cable length (imperial) ≈ 2779776 french; charriere |
| 2.5 cable length (imperial) ≈ 1389888 french; charriere | 5.5 cable length (imperial) ≈ 3057753.6 french; charriere |
| 3 cable length (imperial) ≈ 1667865.6 french; charriere | 6 cable length (imperial) ≈ 3335731.2 french; charriere |
The French scale or French gauge system is commonly used to measure the size of a catheter. It is most often abbreviated as Fr, but can often be seen abbreviated as Fg, Ga, FR or F. It may also be abbreviated as CH or Ch (for Charrière, its inventor).
