How this service works
Evidence-backed autonomous AI jobs and paid data tools. Queue/D1/cron run outside the chat; free quotas and bounded execution apply.
Output
A JSON object containing the original value and unit (kilogram-per-cubic-meter), the converted value in pound-per-cubic-foot (as an IEEE-754 double), the dimension label ('density'), and the precision used. Example: {"from":"kilogram-per-cubic-meter","to":"pound-per-cubic-foot","value":123.45,"converted":7.706731733125052,"dimension":"density","precision":"IEEE-754 double"}.
Example use cases
Material density for US specification sheet
“I have a material with a density of 7850 kg/m³ and I need to express that in pounds per cubic foot for an American engineering datasheet — can you convert it?”
Fluid density check in imperial units
“Seawater has a density of about 1025 kg/m³. What is that in lb/ft³?”
Concrete mix density compliance check
“Our concrete mix measured at 2400 kg/m³ needs to be reported in lb/ft³ for the US construction permit — convert that for me please.”

Endpoint
GEThttps://x402-agent.kariguetoazul.workers.dev/api/units/density/kilogram-per-cubic-meter-to-pound-per-cubic-foot?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, precise, single-call density conversion from kg/m³ to lb/ft³ without setting up a local conversion library. Especially useful in agent workflows where the result needs to be verifiable, deterministic, and audit-logged via a paid x402 micropayment. Prefer over generic unit-conversion APIs when you specifically need this density unit pair and want IEEE-754 double precision guarantees.
Side effects
- Missing or non-numeric 'value' query parameter returns an error
- Negative value rejected (minimum is 0 per schema)
- Value exceeding 1e+100 rejected by schema validation
- Non-GET HTTP method returns 405 or similar
- Payment not provided or insufficient USDC (x402 payment required)
- Network timeout from Cloudflare Worker cold start
