Convert between µg, mg, g, kg, oz, lb and st. Precision, swap, copy and download included.
Built from authoritative conversion constants. Useful for cooking, shipping, lab notes and quick checks.
The Mass & Weight Converter allows you to instantly convert between common units of mass and weight, including grams (g), kilograms (kg), milligrams (mg), ounces (oz), and pounds (lb). This tool is useful for students, cooks, travelers, scientists, and anyone needing accurate and quick unit conversions.
Students, teachers, chefs, fitness enthusiasts, travelers, engineers, and scientists who frequently work with mass or weight measurements.
Converted Value = Input Value × Conversion Factor
Example: converting 5 kg to pounds:
5 × 2.20462 = 11.0231 lb.
Problem: Convert 250 grams to ounces.
Step 1: Use the gram → ounce factor: 1 oz = 28.3495 g.
Step 2: 250 g ÷ 28.3495 ≈ 8.818 oz.
1. Are mass and weight the same?
In everyday usage, yes. In physics, weight refers to force due to gravity, while mass is the amount of matter.
2. How accurate are the conversions?
They use industry-standard conversion factors, typically accurate to at least 4–6 decimal places.
3. Can I convert to stones?
Yes — 1 stone = 14 pounds. The converter supports stones as well as pounds and kilograms.
4. Why are my results rounded?
To keep results readable. Most converters allow choosing the number of decimal places.
5. Does the tool support micrograms?
Yes — µg, mg, g, and kg conversions are supported for scientific and medical measurements.
6. Do I need to know the conversion factor?
No — the tool applies the correct factor automatically.
7. What if I need troy ounces?
Troy ounces differ from standard ounces (used in cooking or weight). Check if your converter supports them or use a precious-metals converter.
8. Can this convert very large weights?
Yes — convert tons, kilograms, or large scientific values using standard factors.
9. Can I convert between imperial and metric easily?
Absolutely — the tool specializes in quick metric–imperial conversions like kg ↔ lb or g ↔ oz.
10. Is this converter free to use?
Yes — most implementations are free, simple, and accessible on any modern device.
This Mass & Weight Converter provides general-purpose conversions for cooking, education, travel, and everyday use. For scientific or engineering applications requiring precise standards, consult official measurement tables or technical documentation.
