Weight Volume Percent Calculator

What is Weight Volume Percent Calculator?

Weight volume percent (w/v %) shows how much mass sits in a volume.
It tells percent grams per 100 mL.
Use it to mix lab solutions, food, or medicine.
The calculator takes mass in grams.
Then it takes volume in milliliters.
It divides mass by volume.
Next it multiplies by 100.
You get percent w/v.
The tool saves time and avoids error.

why to calculate weight volume percent

Imagine Anna. She makes a sports drink for her son.
She adds 5 g salt to 250 mL water.
She asks: what percent salt is that?
You want a clear number.
You want safe mixing.
You use the percent to match a recipe or a label.

Calculate the example step by step

First, know formula: w/v % = (mass in g ÷ volume in mL) × 100.
Secondly, plug values: mass = 5 g. Volume = 250 mL.
Third, divide: 5 ÷ 250 = 0.02.
Fourth, multiply: 0.02 × 100 = 2.
Result: the drink is 2% w/v salt.
That is easy to check by hand.

Final Words

Quick trick: divide grams by mL, then move decimal two places right for percent. Therefore, the calculator stays handy for speed and safety. Finally, use it when you need exact mix.
