The mass unit pound as used in the Imperial unit system and the United States customary unit system is today strictly defined as exactly having the conversion factor of 0.45359237 kg/pound. Therefore, in order to arrive at the mass in kg, all we need to do is to take the mass in pounds and multiply it by the conversion factor 0.45359237 kg/pound which will then provide us with the mass in kg. In this case, we can mathematically express it as,

14 pounds = 14 pounds * 0.45359237 kg/pound = 6.35029 kg.

Therefore, 14 pounds is equal to 6.4 kg (keeping the number of significant digits to 2 as given by the formulation of the question).

I hope this answers your question and helps you to in the future more easily convert between the Imperial pound mass unit and the metric kg mass unit. Good luck!

To convert from pounds to kilograms, multiply the number of pounds by 0.4536.

Using this formula, we get:

kg = 14*0.4536

kg = 6.3504

Therefore, 14 pounds = 6.35 kg

For every 1 pound, there are 0.455359237 Kilograms

14 pounds will be equivalent to (14/1) * 0.455359237 = 6.375 kg
