**How to Convert Metric Measurements to U.S. Measurements**

- 0.5 ml = ⅛ teaspoon.
- 1 ml = ¼ teaspoon.
- 2 ml = 1/3 teaspoon.
- 5 ml = 1 teaspoon.
- 15 ml = 1 tablespoon.
- 25 ml = 1 tablespoon + 2 teaspoons.
- 50 ml = 2 fluid ounces = ¼ cup.
- 75 ml = 3 fluid ounces = ⅓ cup.

## How would you make 50ml of a 1 5 dilution?

1. You need to make a 1:5 dilution of a solution. You need 10 ml of the diluted solution.

- (initial concentration)(initial volume) = (final concentration)(final volume)
- (12x)(X ml) = (3x)(200 ml)
- X ml = (3x)(200 ml) / 12x.
- X ml = 50 ml of 12x TBE.

## How do you calculate dilution?

**The formula for calculating a dilution is (C1) (V1) = (C2) (V2) where**

- C1 is the concentration of the starting solution.
- V1 is the volume of the starting solution.
- C2 is the concentration of the final solution.
- V2 is the volume of the final solution.

## How do you calculate liquid mix ratio?

**Divide 1 by the total number of parts (water + solution)**. For example, if your mix ratio is 8:1 or 8 parts water to 1 part solution, there are (8 + 1) or 9 parts. The mixing percentage is 11.1% (1 divided by 9).
