Green Sea Turtle Body Condition Calculator

Enter weight and curved carapace length. The calculator converts CCL to estimated SCL, then calculates Fulton’s Body Condition Index.

Weight in kilograms Curved Carapace Length — CCL in centimetres Calculate Body Condition

Formulae: SCL = 0.294 + (0.937 × CCL). Fulton’s BCI = Weight ÷ SCL³ × 10,000. A BCI of 1.20 or above is commonly used as a practical threshold for good condition in juvenile and adult Green turtles.
