How long is 100g of hair?

The length of 100 grams of hair can vary significantly depending on the thickness and type of hair. On average, human hair weighs about 0.02 grams per centimeter, so 100 grams of hair could be approximately 5,000 centimeters, or 50 meters, if considering average thickness. However, this is a rough estimate, as individual hair characteristics can lead to different lengths.
