A FRIEND SAID THAT ATMOSPHERIC PRESSURE OR BAROMETRIC PRESSURE CHANGES CAN AFFECT THE RESULTS OF MY STEPPING ON THE BATHROOM SCALE. IS THIS TRUE? AND IF SO, WHY? —Preceding unsigned comment added by Gtigue (talk • contribs) 00:37, August 30, 2007 (UTC) If atmospheric pressure goes up, your apparent weight will be slightly less, because of ...
Atmospheric pressure, also known as air pressure or barometric pressure (after the barometer), is the pressure within the atmosphere of Earth. The standard atmosphere (symbol: atm) is a unit of pressure defined as 101,325 Pa (1,013.25 hPa ), which is equivalent to 1,013.25 millibars , [ 1 ] 760 mm Hg , 29.9212 inches Hg , or 14.696 psi .

The term bariatrics was coined around 1965, [2] from the Greek root bar- ("weight" as in barometer), suffix-iatr ("treatment," as in pediatrics), and suffix-ic ("pertaining to"). The field encompasses dieting, exercise and behavioral therapy approaches to weight loss, as well as pharmacotherapy and surgery. The term is also used in the medical ...
Another common body measurement tool is the body mass index (BMI), which makes its calculation from two factors: height and weight. It’s still widely used by the medical community to determine ...
For example, if a barometer located at sea level and under fair weather conditions is moved to an altitude of 1,000 feet (305 m), about 1 inch of mercury (~35 hPa) must be added on to the reading. The barometer readings at the two locations should be the same if there are negligible changes in time, horizontal distance, and temperature.
For instance, buoyancy's diminishing effect upon one's body weight (a relatively low-density object) is 1 ⁄ 860 that of gravity (for pure water it is about 1 ⁄ 770 that of gravity). Furthermore, variations in barometric pressure rarely affect a person's weight more than ±1 part in 30,000. [ 6 ]
Human body weight is a person's mass or weight. Strictly speaking, body weight is the measurement of mass without items located on the person. Practically though, body weight may be measured with clothes on, but without shoes or heavy accessories such as mobile phones and wallets, and using manual or digital weighing scales .
Attitudes toward body weight held by people in one's life may also play a role in obesity. A correlation in BMI changes over time has been found among friends, siblings, and spouses. [153] Stress and perceived low social status appear to increase risk of obesity. [152] [154] [155] Smoking has a significant effect on an individual's weight.
