Basal metabolic rate calculation.

Hi,

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

https://lemmy.today/pictrs/image/1d712db3-03ff-4890-a08c-1f5bf60dbc0b.png

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.

magiccupcake,

Looks like the conservation to cm is written wrong in the wiki article.

66 in is closer to 168 cm, putting that into the equation for h yields the expected 1204

parasocialite,

That’s interesting. I was going to edit the wiki page to correct the error, but the wiki code in the article is: {{convert|66|in|cm}} so their underlying converter is what’s producing that inaccurate value.

magiccupcake,

Seems like it’s overly aggressive rounding.

According to chatgpt you can specify to the zeroth decimal which makes it display 168

{{convert|66|in|cm|0}}

parasocialite,

Fixed it. There was no precision specified in the conversion.
