Hi,

I've found on Wikipedia the following formula to calculate the BMR estimation

We can read just after the formula:

According to this formula, the woman in the example above has a BMR of 1,204 kilocalories (5,040 kJ) per day.

But when I take their example of a 55-year-old woman weighing 130 pounds (59 kg) and 66 inches (170 cm)

and do ((10*55)+(6,25*170)-(5*55))-161 I get 1,217 and not 1,204

Am I doing something wrong ?

Thanks.

((10 × 55) + (6.25 × 170) − (5 × 55)) − 161 = 1176.5

((10 × 59) + (6.25 × 170) − (5 × 55)) − 161 = 1216.5

((10 × 59) + (6.25 × 168) − (5 × 55)) − 161 = 1204

66 "inches" is 167.64 cm. Maybe, at some point, let's stop using bullshit units. People are bad enough already at math without that...
