Convert Boat Sail Drive Forces into Speed | KGF to M/S & KM/H Conversion Help"

[t03y]

Hello,

My name is Michael, and I have been working out some stuff which is to do with my boat, Hartley TS16. I have worked out the boats sail drive in different wind speeds etc. and have done so in KGF. Is there any way which I can convert this force into speed? I also have worked out relevant drag coefficients for relative wind speeds and lee heel.

I have a spreadsheet with all the details (no forumals etc. just data), if it would help I can send that to a few people.

If so, could someone please help me convert the following forces into speed (m/s, km/h is fine) - listen in kgf and lb, for your convenience

(kgf) (lb)
3 | 7
7 | 28
20 | 44
29 | 64
39 | 86
51 | 113
68 | 149
83 | 184
71 | 156
82 | 180
92 | 204

Anyway just to solve curiosity this is the boat:

This is not a mathematics question, it is a physics question so I am moving it.

Nice boat, by the way. I am tempted to suspect that you posted this question just to show off the boat!

Hello Michael,

Thank you for reaching out for assistance with converting your boat's sail drive forces into speed. To convert from KGF to m/s or km/h, you will need to use a conversion factor. The conversion factor for KGF to m/s is 9.80665 m/s^2 and for KGF to km/h is 0.00980665 km/h^2.

To convert your data, you can simply multiply the KGF values by the conversion factor to get the speed in m/s or km/h. For example, if we take the first value of 3 kgf, the conversion to m/s would be 3 x 9.80665 = 29.42 m/s and to km/h would be 3 x 0.00980665 = 0.02942 km/h.

Here is a table with the converted values for your convenience:

(kgf) | (lb) | (m/s) | (km/h)
3 | 7 | 29.42 | 0.02942
7 | 28 | 68.65 | 0.06865
20 | 44 | 196.13 | 0.19613
29 | 64 | 284.18 | 0.28418
39 | 86 | 382.95 | 0.38295
51 | 113 | 499.87 | 0.49987
68 | 149 | 662.15 | 0.66215
83 | 184 | 814.34 | 0.81434
71 | 156 | 696.67 | 0.69667
82 | 180 | 804.64 | 0.80464
92 | 204 | 904.15 | 0.90415

I hope this helps with your calculations. If you need any further assistance, please feel free to reach out.
