# Reference for the bite force for Nile Crocodile

The (maximal) bite force of the Nile Crocodile (Crocodylus niloticus) is estimated around 22,000 Newton (refer to YouTube interview with Ofer Kobi, a crocodile conservation ranger and croc farm owner, time 7:50-8:00, Hebrew , where he estimates the bite force as above 2 metric tons). However, I didn't find a proper reference for this. Dr. Gregory Erickson measured the bite forces of a 5.2 meters long Saltwater Crocodile (Crocodylus porosus) and obtained a value of about 16,000+ Newton and estimated a 6.7 meters long Saltwater Crocodile can exert a bite twice as strong (about 34,000 Newton). See Paper by Gregory Erickson et al. Interesting to note that Erickson measured small Nile Crocodile (total body length < 3 meters) so it does not represent the bite force of a full adult big crocodile.

Remarks on units of force:

1 Newton = 1 kg * 1 meter / sec^2

$1 \ \mathrm{Newton} = \frac{\mathrm{kg} \times \mathrm{meter}}{\mathrm{second}^2}$

1 Newton = 0.224808943 lbf = 0.225 lbf (pound-force)

10,000 Newton is approximately 1 tonne-force (1 tonne = 1 metric ton = 1000 kg)

• Where did you get your estimates from? Jun 18, 2018 at 20:13
• From an interview with an owner of a crocodile farm. Jun 24, 2018 at 17:18
• An interview you've conducted yourself? An interview that has been diffused on TV? Do you have a link to this interview or some document where we can find direct quote or something? Jun 24, 2018 at 21:25
• No, an interview on TV. It was held in Hebrew. Since he is not a scientist I am looking for a better reference for the bite force of a Nile Crocodile. It seems strange that no body measured the bite force of a 5+ meters nile croc. Jun 25, 2018 at 17:26
