How this service works
Convert between weight and mass units: metric tons, kilograms, grams, milligrams, pounds, ounces and stones with exact international definitions. Use this when an agent needs to kilograms, pounds, ounces and more.
Output
Returns the converted numeric value in the target weight unit, computed using exact international definitions for each unit (e.g. 1 pound = 0.45359237 kg exactly).
Example use cases
Shipping weight label conversion
“I have a package that weighs 3.5 kg — what's that in pounds and ounces so I can fill out the US shipping label?”
Recipe ingredient scaling
“My recipe calls for 250 grams of flour but my kitchen scale only does ounces — how many ounces is that?”
Fitness tracker unit switch
“My gym tracks body weight in stones but I want to log in kilograms — I'm 13 stones, what's that in kg?”
Technical details
Endpoint
GEThttps://agenttools-hub.vercel.app/api/v1/converters/weight-converter?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a deterministic, exact weight or mass unit conversion between the seven most common units (metric tons, kg, g, mg, lb, oz, stones) without relying on an LLM approximation. Ideal for agents handling shipping, nutrition, fitness, or scientific data where precision matters and a simple GET call is preferred over a general-purpose math tool.
Side effects
- Missing required query parameters (value, from, to) returns a 400 error
- Unsupported unit codes outside the enum (t, kg, g, mg, lb, oz, st) are rejected
- Non-numeric value parameter causes a validation error
- Same-unit conversion (from === to) should return the original value but may behave unexpectedly
