What is the mass in kilograms of a person weighing 170 pounds?

Answer 1

77.3 kilograms

A person lucky enough to weigh only 170 pounds is one who possesses a mass that, being acted upon by Earth's gravity, results in a downward pull of 170 pounds-force (lbf, English units). If this lucky person just jumped out of a perfectly good airplane, or is walking on the Moon, then his weight is out the window, and changeable. Mass, however, remains the same, until you hit the age of 35 or 40!!

In the English system of physical units, a body near sea level on Earth weighing 170 lbf would also have a mass of 170 lbm (pounds-mass.)

The conversion from kilogram (System International metric system mass) to English pounds-mass is as follows:

1 kilogram (kg) = 2.2 pounds-mass (lbm)

or 1 kg = 2.2 lbm

or 1 lbm = 0.455 kg

Substituting 170 lbm, (170 x 0.45) = 77 kg

The mass in kilograms of a person weighing 170 pounds is about 77.

A 1,000 pound barbell may be easily lifted while in orbit on the space shuttle. But it is not easily kicked when bare-footed. This is the difference between weight and mass.

Answer 2

To convert pounds to kilograms, you can use the conversion factor of 1 pound = 0.453592 kilograms. Therefore, a person weighing 170 pounds would have a mass of approximately 77.273 kilograms.
