Frequently Asked Questions
What is the difference between volume and capacity?
Volume is the amount of 3D space occupied. Capacity is how much a container can hold. A box has volume; a bottle has capacity.
What are key metric conversions?
1000 mL = 1 L, 1000 L = 1 kL. Also, 1 mL = 1 cm³ (cubic centimeter).
What are key imperial conversions?
8 fluid ounces = 1 cup, 2 cups = 1 pint, 2 pints = 1 quart, 4 quarts = 1 gallon. 1 gallon ≈ 3.8 liters.
