Grams to Micrograms (G to MCG) Converter Online
Use this free grams to micrograms converter to instantly change g to mcg (µg) with 100% accurate results. Just enter your value in grams, and the tool will show you the exact amount in micrograms. Below the calculator, we also explain how to convert grams to micrograms manually using the simple g to mcg formula, so beginners and students can understand the conversion step by step.
How Do You Convert Gram to Microgram?
To convert grams to micrograms, you always multiply the value in grams by 1,000,000 (10⁶). A microgram (mcg or µg) is much smaller than a gram, so you need a big number of micrograms to equal just one gram. That’s why 1 gram = 1,000,000 micrograms. This simple rule is the base of every g to mcg or g to µg conversion, whether you’re using an online grams to micrograms converter or doing the calculation manually.
Grams to Micrograms Formula
The standard grams to micrograms formula is:
- micrograms (mcg or µg) = grams (g) × 1,000,000
- µg = g × 10⁶
So whenever you see g to mcg or g to µg, just remember:
✔️ Take the number of grams
✔️ Multiply it by 1,000,000
✔️ The answer is in micrograms (mcg or µg)
Accuracy & Rounding for G to CG Conversion
This converter uses the exact SI constant: 1 g = 100 cg.
All calculations are precise up to the full decimal range, and results are rounded only for display.
Precision: Use 2–4 decimals for general use; scientific reporting may use 4–6.
Constant: 1 cg = 0.01 g (exact).
Tip: Match your output precision to your input’s significant figures.
Locale aware: Decimal separator (dot/comma) adapts to regional settings automatically.
For educational or lab use, show whole-number centigrams when inputs are small (< 1 g) for readability.
Units and Standards
Gram (g): Base metric unit of mass equal to 1/1000 kilogram.
Centigram (cg): Sub-unit equal to 1/100 of a gram.
Metric relationship: cg = g × 100 and g = cg ÷ 100.
System: International System of Units (SI).

Some Relavant Question About G to CG Converter
Converting grams to centigrams is simple. Since 1 gram = 100 centigrams, you just multiply the number of grams by 100. For example, 5 g × 100 = 500 cg. This method ensures quick and accurate results without any complex formulas.
To use multiplication, multiply grams by 100 → cg = g × 100.
To use division, divide centigrams by 100 → g = cg ÷ 100.
Both methods work depending on the direction of your conversion — from grams to centigrams or vice versa.
There are exactly 100 centigrams in one gram. The prefix “centi” means one-hundredth, so 1 gram = 100 × 0.01 grams = 100 centigrams.
Yes, it is. When you divide 2000 centigrams by 100, you get 2 grams. This shows how easily you can switch between the two units within the metric system.
You can find centigrams by multiplying the grams by 100:
7 g × 100 = 700 cg
12 g × 100 = 1200 cg
This simple formula applies to any conversion from grams to centigrams.
A centigram (cg) is one-hundredth of a gram. Numerically, 1 cg = 0.01 g, making it a smaller metric unit used for precise weight measurements, such as in laboratories or scientific calculations.
To convert 100 grams to centigrams, multiply 100 × 100 = 10,000 centigrams. This helps visualize how grams and centigrams scale within the metric conversion system.
