How this service works
Casting weight in grams, pennyweight and troy ounces from volume or wax model weight, for gold, silver, platinum and more.
Output
Returns the piece weight in grams, pennyweight (dwt), and troy ounces, along with total weight including waste, volume in cm³, the wax-to-metal conversion factor used, metal density in g/cm³, and a summary. May include a disclaimer if operating in degraded mode.
Example use cases
Lost-wax casting material estimate
“My wax model weighs 3.8 grams and I want to cast it in sterling silver — what will the finished piece weigh in grams and troy ounces, and how much extra metal should I order for a 15% sprue waste?”
Platinum ring volume-based weight calc
“I have a platinum ring design with a volume of 2.4 cubic centimetres — how much will it weigh in grams and pennyweight after casting?”
Comparing gold alloy casting weights
“If my wax model is 5 grams, what would the casting weight be in grams and troy ounces for 18k yellow gold versus 14k white gold? Use a standard wax density.”
Technical details
Endpoint
GEThttps://jewelry-calc.x402tookit.com/metal-weight?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to convert a wax model weight or known piece volume into casting metal weight for jewelry production. It supports 15+ specific metal alloys with real density data and handles lost-wax casting conventions (wax density, sprue waste). Prefer this over generic unit converters when you need jewelry-specific outputs like pennyweight and proper alloy density.
Side effects
- Missing required 'metal' query parameter returns an error
- None of waxGrams, volumeCm3, or volumeMm3 provided — endpoint cannot compute without at least one volume/weight input
- Invalid metal identifier (not in the allowed enum) causes a validation error
- Very large or zero volume/wax values may return implausible results without explicit error
