Introduction - Incorrect unit conversion #66

Open zuzi-m opened 2 years ago

zuzi-m commented 2 years ago

On line number 15 of the introduction page source it incorrectly says eight pints [17kg] of water

8 pints of water is roughly ~4.5 liters (that is if you used UK pints, or ~3.7 liters if you used US pints) and roughly the same in kilograms. But in the text mentioned above it incorrectly states 17kg

The error is repeated again on line 18 where it says ...the average adult human has 17 kg blood and... (I also believe there should be no space between 17 and "kg" as it is a quantity with its unit of measure. Lastly, I suggest saying "of blood" instead of just "blood")

According to the brochure of the International System, there should be a space between the number and the unit (with exception for the symbols for degrees, minutes and seconds, that is the little circle, the single quote and the double quote).

5.4.3 Écriture de la valeur d’une grandeur La valeur numérique précède toujours l’unité et il y a toujours une espace entre le nombre et l’unité. https://www.bipm.org/documents/20126/41483022/SI-Brochure-9.pdf

Thanks for clarifying

In that case I would suggest adding spaces between the numbers and their units in the paragraph that is on line number 15 in the text source - there are a few instances of numbers and their units without a space
