Conversion Formula
Price per Gram = Price per Kilogram / 1000
Price per Kilogram = Price per Gram x 1000
- “Price per Gram” is the cost per gram
- “Price per Kilogram” is the cost per kilogram
- One kilogram equals exactly 1,000 grams

The Retail Premium on Gram Pricing
Dividing a kilogram price by 1,000 gives the theoretical gram price at the same margin. In practice, retail gram prices run 20 to 400% above this figure. The gap reflects packaging, handling, and small-quantity overhead that bulk kg buyers do not pay. A specialty coffee roaster paying $7/kg wholesale ($0.007/g) typically retails a 200g bag at $0.025 to $0.040/g, roughly 3 to 6x the bulk conversion. The premium is widest in high-value spices: saffron wholesale at $3,000/kg ($3.00/g) retails at $6 to $12/g, a 2 to 4x markup at the gram level. The simple division formula is accurate for unit conversion but understates the actual gram price consumers pay.
Who Uses This Conversion
Three industries rely on this conversion most frequently. Precious metals dealers quote wholesale in kilograms but sell retail in grams. Specialty food importers receive commodity invoices priced per kilogram and must convert to per-gram retail pricing. Pharmaceutical and supplement manufacturers cost raw active ingredients in $/kg for procurement but calculate per-dose cost at the milligram level, making the intermediate gram price a key checkpoint. In each case the formula is the same: divide the kilogram price by 1,000.
Conversion Examples
$20/kg (ground black pepper): $20 / 1000 = $0.020 per gram
$3,000/kg (saffron, wholesale): $3,000 / 1000 = $3.00 per gram
$164,000/kg (gold, early 2026): $164,000 / 1000 = $164.00 per gram
Reverse: $1.03/g (silver spot): $1.03 x 1000 = $1,030 per kilogram
