   Charriere

Conversion units Charriere

 

Charriere

Symbol is: Ch or CH

Synonym

French gauge

Definition

Unit which expresses the external diameter in ⅓ mm where:

 

CH N° divided by 3 = ext. diameter in mm

 

Examples: CH6 = 2mm

 

                  CH4 = 1.33mm

Field of use

Tubes and drains.

French

Symbol is: F or FG

Synonym

French size, french gauge, charriere.

Definition

Unit which expresses the external diameter in ⅓ mm where:

 

1 FG = 1 CH = ⅓ mm

 

Attention: Some manufacturers offer catheters measured in INCHES.

 

Example: 5 FG = CH5 = 1.66mm = 0.066 INCH

Field of use

Exploratory catheters, tubes and drains.

Gauge

Symbol is: G, Ga, Gg, g

Synonym

British standard gauge.

Definition

Unit which expresses the external diameter of the object, in a range from 8 to 30, corresponding respectively to 4 and 0.3mm.

 

Attention: The gauge/mm correspondence may vary, due to figures being rounded off in conversion from inches to mm.

 

The higher the gauge, the smaller the external diameter.

 

The gauge gives the external diameter, but does not take account of the thickness of the wall, so does not give an idea of the external diameter.

 

Examples: 22G = 0.7 to 0.9mm

 

                 18G = 1.1 to 1.3mm

Field of use

Short catheters, needles, micro-perfusers.

Inch

Symbol is: In or "

Synonym

In french: pouce

Definition

Unit used to express the external diameter of guides.

 

Examples: 1 in = 1 inch = 25.4mm

 

                  1mm = 0.04 in = 0.04"

Field of use

Guides for catheters.

Plasteau-benique

Symbol is: P.B

Synonym

Benique.

Definition

The Plasteau-Benique measurement corresponds to half of the charriere measurement.

 

Unit which expresses the external diameter in 1/6 mm.

 

P.B N° divided by 6 = ext. diameter in mm

 

Example: 40 P.B = 20CH = 6.66mm

Field of use

Tubes for urology.
