Convert gold weight to currency value

Gold Pricing Unit Variations

Gold is priced per ounce in global markets (Fix, COMEX). Regional markets sometimes use grams (most of Asia) or tolas (traditionally 10 grams). One troy ounce equals 31.1035 grams.

Purity Matters

Jewelry is rarely 24K pure. Common purities: 24K (99.9%), 22K (91.7%), 18K (75%), 14K (58.3%). Market price refers to 24K. Multiply by purity fraction for other karats. A 10g 22K piece has an effective pure gold content of 9.17 grams.

Run it with sensible defaults

Using weight of 10, price per unit of 2,000, grams per input unit of 1, the calculation works out to 20,000.00. Nudge the inputs toward your own situation and the output recalculates instantly. The defaults are meant as a starting point, not a recommendation.

The levers in this calculation

The inputs — Weight, Price Per Unit, and Grams Per Input Unit — do not pull with equal force. Frequency and unit price pull the total in different directions. The biggest surprise for most people is how small recurring amounts compound into large annual figures — that's where this calculation earns its keep.

How the math works

Multiplies weight by price per unit. Grams-per-unit allows conversion between units (e.g., 31.1035 for ounces). The working is transparent — you can verify every step yourself in the formula section below. No black box, no opaque "proprietary model".

Why run the calculation

Utility bills creep. Small annual increases stack into meaningful differences over a decade. Running this once a year and switching providers when the gap widens is one of the easiest ways to keep household costs in check.

What this doesn't capture

Usage varies month-to-month; tariffs change; discounts come and go. The figure here is a clean baseline — your actual annual bill will fluctuate around it. Use the calculation to benchmark providers, not as a prediction of a specific bill.
