Frequently Asked Questions

How do you convert ounces to ml?
To convert ounces to milliliters, multiply the number of ounces by 29.5735 for US fluid ounces or by 28.4131 for UK imperial fluid ounces. For example: 2 US fl oz × 29.5735 = 59.147 mL.
How do you convert ml to ounces?
To convert milliliters to ounces, divide the number of milliliters by 29.5735 for US fluid ounces or by 28.4131 for UK imperial fluid ounces. Alternatively, multiply by 0.033814 (US) or 0.035195 (UK).
How many ounces to ml?
1 US fluid ounce equals 29.5735 mL, while 1 UK imperial fluid ounce equals 28.4131 mL. The US ounce is slightly larger than the UK ounce.
How many ml in 8 oz?
8 US fluid ounces equal 236.588 mL (8 × 29.5735), while 8 UK imperial fluid ounces equal 227.305 mL (8 × 28.4131).
Is 100 mL the same as 3 oz?
100 mL equals approximately 3.38 US fluid ounces or 3.52 UK imperial fluid ounces. So 100 mL is slightly more than 3 ounces in both systems.
How accurate are mL to ounce conversions?
Our converter uses the exact conversion factors: 1 US fl oz = 29.5735295625 mL and 1 UK fl oz = 28.4130625 mL. This provides accuracy to multiple decimal places, suitable for all applications including scientific and medical use.

Understanding Liquid Measurements

What is a Milliliter?

A milliliter (mL) is a metric unit of volume equal to one thousandth of a liter. It's widely used in scientific, medical, and culinary applications worldwide. The milliliter is part of the International System of Units (SI) and provides precise measurements for small volumes.

What is a Fluid Ounce?

A fluid ounce (fl oz) is a unit of volume used primarily in the United States and United Kingdom. Despite sharing the same name, US and UK fluid ounces have different volumes:

  • US Fluid Ounce: Used in the US customary system, equals 1/16 of a US pint
  • UK Imperial Fluid Ounce: Used in the imperial system, equals 1/20 of an imperial pint

Conversion Tips and Best Practices

  • Always specify the system: Clarify whether you're using US or UK measurements
  • Round appropriately: For cooking, 2-3 decimal places are usually sufficient
  • Use precise conversions for medicine: Medical dosages require exact measurements
  • Consider temperature effects: Volume can change with temperature, though the effect is minimal for most purposes
