How It Works
This converter works in 3 steps.
Enter the volume
Type the number.
Choose the source unit
Select µL, mL, L, tsp, tbsp, fl oz, cup, pint, quart, or gallon (US or imperial).
Read all units
The converter converts to mL first and then to every other unit.
Pick a practical measure
Use the unit that matches the measuring tool at hand.
The Formula
The formula converts the source volume to milliliters and then divides by each target unit's mL value.
V_target = V_source × (mL per source unit) / (mL per target unit)1 US gal = 128 US fl oz = 3,785.41 mL1 tbsp = 3 tsp = 14.79 mL- V_source:
- Volume entered
- V_target:
- Volume in the chosen unit
A label calls for 2 fl oz per gallon. 2 × 29.57 = 59.1 mL per 3,785 mL, which equals 15.6 mL per liter.
Conversion Table
The conversion table lists 8 household volume units in mL, L, and US fl oz.

| 1 US quart | 946.4 | 0.9464 | 32 |
| 1 US gallon | 3,785 | 3.785 | 128 |
| 1 imperial gallon | 4,546 | 4.546 | 153.7 |
What Is the Dilution Volume Unit Converter?
The Dilution Volume Unit Converter is a tool that converts volumes between laboratory units (µL, mL, L) and household units (teaspoon, tablespoon, fluid ounce, cup, quart, gallon). One US gallon equals 3,785.41 mL, and one US fluid ounce equals 29.57 mL.
Product labels in the United States give dilution amounts in ounces per gallon or tablespoons per quart, while lab protocols use mL. US and imperial units differ: 1 imperial gallon is 4,546 mL, about 20% more than a US gallon. The converter labels every unit as US or imperial.
