Use our free Weight Converter/Weight Unit Converter to instantly convert Atomic Mass Unit, Carat, Gram, Kilogram, Ounce, Pound, Ton, and Tonne. Simple, reliable, and online.
Weight or mass conversion is crucial in science, engineering, business, and day-to-day life. You are a student, engineer, chef, or tourist, and you need to rely on a trustworthy Weight Converter or Weight Unit Converter tool to save time and achieve accuracy.
The SEO Pheonix Weight ConverterWeight Converter Calculator allows you to convert measurements such as Atomic Mass Unit (amu), Carat (metric), Gram, Kilogram, Milligram, Microgram, Ounce (mass and troy), Pound (mass and troy), Ton (short, long, metric, assay), and Tonne immediately — all at one handy location, free online.
Weight and mass are two associated but different concepts:
Mass (symbol: m) is a measure of the amount of matter in an object and is typically given in grams, kilograms, or atomic mass units.
Weight (symbol: W) is the gravitational force acting on that mass:
W=m×g
Where:
W = Weight (Newtons)
m = Mass (kg)
g = Acceleration due to gravity (~9.81 m/s²)
In most ordinary usage, we tend to use the terms weight and mass interchangeably, particularly in cooking, shipping, and general conversions.
A Weight Converter or Weight Unit Converter is a program that helps to convert a unit of weight or mass from one unit to another. The contemporary web-based aids are programmed to deal with both metric and imperial units, which simplifies the calculation process and improves accuracy.
Two popular forms of weight converters:
Online Measurement Converter: Deals with units such as Gram → Kilogram, Pound → Ounce, Ton → Tonne, etc.
Physical Converter/Scale: Transfers the measured weight reading between systems (e.g., kilograms to pounds on a scale).
In this section, we concentrate on measurement-based weight conversion for science, industry, and everyday application.
Here's the detailed unit breakdown supported by the SEO Pheonix Weight Converter:
| Unit Name | Symbol | Description |
| Atomic Mass Unit | amu | Small unit for atoms and molecules. 1 amu ≈ 1.6605 × 10⁻²⁷ kg |
| Carat (metric) | ct | Common in gemstones. 1 Carat = 0.2 grams |
| Gram | g | Base metric unit of mass |
| Kilogram | kg | 1 kg = 1000 grams, SI base unit of mass |
| Milligram | mg | 1 mg = 0.001 grams |
| Microgram | μg | 1 μg = 0.000001 grams |
| Ounce (mass) | oz | Imperial unit, 1 oz ≈ 28.3495 g |
| Ounce (troy) | ozt | Used in precious metals, 1 ozt ≈ 31.1035 g |
| Pound (mass) | lb | Imperial unit, 1 lb ≈ 0.453592 kg |
| Pound (troy) | lb t | Used in bullion, 1 lb t = 12 ozt |
| Ton (short) | ton (US) | 1 short ton = 2000 lb ≈ 907.185 kg |
| Ton (long) | ton (UK) | 1 long ton = 2240 lb ≈ 1016.05 kg |
| Ton (metric) | t | 1 metric ton = 1000 kg |
| Ton (assay) | ton (assay) | Used in mining, 1 ton = 29.1667 lb |
| Tonne | t | Same as metric ton = 1000 kg |
Here are some standard conversion equations:
1 kg=1000 g=1,000,000 mg=1,000,000,000 μg
1 g=0.001 kg=1000 mg =1,000,000 μg
1 lb=16 oz
1 ton (short)=2000 lb
1 ton (long)=2240 lb
1 kg≈2.20462 lb
1 g≈0.035274 oz
1 t (metric)≈2204.62 lb
1 carat=0.2 g
1 amu≈1.6605×10−24 g
It is easy to use the SEO Pheonix Weight Converter:
Choose the input unit (e.g., Gram, Pound, Ton).
Enter the value you need to convert.
Select the destination unit (e.g., Pound → Kilogram).
Click "Convert" to receive instant results on this mass converter tool.
The software covers all metric, imperial, troy, and special units such as amu and Carat.
Example 1: Convert 5 Kilograms to Pounds
1kg≈2.20462lb
5×2.20462=11.0231lb
Example 2: Convert 10 Carats to Grams
1ct=0.2g
10×0.2=2g
Example 3: Convert 2 Short Tons to Kilograms
1shortton≈907.185kg
2×907.185=1814.37kg
Example 4: Convert 5000 mg to Kilograms
1mg=0.000001kg
5000×0.000001=0.005kg
Manual weight conversions take time and are liable to error when there are multiple systems such as metric, imperial, troy, or assay units.
