Percentage to Grams Conversion Chart
Percent (%) | Total Mass (g) | Grams (g) | Calculation (Percent × Total Mass / 100) |
---|---|---|---|
0.5% | 1,000 | 5 | 0.5 × 1,000 / 100 = 5 |
1% | 1,000 | 10 | 1 × 1,000 / 100 = 10 |
2% | 1,000 | 20 | 2 × 1,000 / 100 = 20 |
5% | 1,000 | 50 | 5 × 1,000 / 100 = 50 |
10% | 1,000 | 100 | 10 × 1,000 / 100 = 100 |
15% | 1,000 | 150 | 15 × 1,000 / 100 = 150 |
20% | 1,000 | 200 | 20 × 1,000 / 100 = 200 |
25% | 1,000 | 250 | 25 × 1,000 / 100 = 250 |
30% | 1,000 | 300 | 30 × 1,000 / 100 = 300 |
50% | 1,000 | 500 | 50 × 1,000 / 100 = 500 |
75% | 1,000 | 750 | 75 × 1,000 / 100 = 750 |
100% | 1,000 | 1,000 | 100 × 1,000 / 100 = 1,000 |
How to Convert Percent to Grams
To convert from percentage to grams, multiply total solution weight by percentage expressed as a decimal Grams = Total Weight × (Percentage ÷ 100). For a weight/volume solution, use the solution’s density to adjust the calculation. Remember that percentages can be expressed as weight/weight (w/w) or weight/volume (w/v).
- Inputs: Solution = 500 grams, Concentration = 5%
- Calculations: 500 × (5 ÷ 100) = 25
- Result: 25 grams needed for 5% solution
Percent to Grams Formula
Grams = Total Weight × (Percentage ÷ 100)
For w/v solutions:
Grams = Volume × Density × (Percentage ÷ 100)
Where:
Total Weight = Solution weight in grams
Percentage = Desired concentration percentage
Volume = Solution volume in milliliters
Salt Solution
- Inputs: Total weight = 200g, Percentage = 10%, Type = w/w
- Calculations: 200 × (10 ÷ 100)
- Result: 20 grams of salt needed
Sugar Mixture
- Inputs: Total weight = 1000g, Percentage = 25%, Type = w/w
- Calculations: 1000 × (25 ÷ 100)
- Result: 250 grams of sugar needed
Chemical Solution
- Inputs: Total weight = 150g, Percentage = 8%, Type = w/w
- Calculations: 150 × (8 ÷ 100)
- Result: 12 grams of chemical needed
Medical Solution
- Inputs: Total weight = 400g, Percentage = 12%, Type = w/w
- Calculations: 400 × (12 ÷ 100)
- Result: 48 grams of solute needed
Laboratory Sample
- Inputs: Total weight = 50g, Percentage = 20%, Type = w/w
- Calculations: 50 × (20 ÷ 100)
- Result: 10 grams of sample needed
What is Percentage and Grams?
Percentage (%): A dimensionless ratio expressing a number as a fraction of 100, used to describe concentration or proportion in solutions.
Percentage = (Part ÷ Whole) × 100
Grams (g): The standard unit of mass in the metric system, equal to one-thousandth of a kilogram.
1 gram = 1000 milligrams = 0.001 kilograms
