FAQ
Why do US and UK differ?
They defined fluid ounces differently historically. Always match the system on your recipe or label.
Is a fluid ounce the same as a weight ounce?
No. Fluid ounces are volume; ounces (oz) on a scale are mass.
What cup size is shown?
A 240 mL US cup convenience. Some nutrition labels use 240 mL; older cups vary.
Medicine syringes?
Use the mL markings on the syringe — do not convert through kitchen spoons for dosing.
