Formula Used
We normalize the package weight to grams and compute a base unit price:
price_per_gram = total_price / weight_in_grams
price_per_kilogram = price_per_gram × 1000
price_per_pound = price_per_gram × 453.59237
price_per_ounce = price_per_gram × 28.349523125
price_per_100g = price_per_gram × 100
Conversions: 1 kg = 1000 g; 1 lb = 453.59237 g; 1 oz = 28.349523125 g.
