By using a scale and putting it on the Oz's setting.
A small can of applesauce weighs 15 oz.
15 percent of 24 oz = 3.6 oz 15% of 24 oz = 15% * 24 oz = 15%/100% * 24 oz = 0.15 * 24 oz = 3.6 oz
Those two units of measure do not convert. One is weight or mass and the other is volume.
Nina can measure 32 oz of water by using her 16 oz bottle twice, and then measuring out 7 oz from the 32 oz with her cup measure.
15 mls = 0.51 fl oz (US).15 mls = 0.51 fl oz (US).15 mls = 0.51 fl oz (US).15 mls = 0.51 fl oz (US).
Depending upon where you are: In UK: 28.4 ml ≈ 1 fl oz → 15 ml ≈ 15 ÷ 28.41 fl oz ≈ 0.53 fl oz In USA: 29.57 ml ≈ 1 fl oz → 15 ml ≈ 15 ÷ 29.57 fl oz ≈ 0.51 fl oz
24 oz is a measure of weight (like 700g) 24 fl oz is a measure of volume (like 700ml)
15 fl oz is 443.6cc
15 grams = 0.529 oz The formula if needed - 15 g* 1 oz 28.34952313 g = 0.5291094292 oz
15 oz = 1-7/8 (or 1. 875) cups
15 US fl oz = 0.444L
3.4 fl oz is a measure of volume while 3.4 oz is a measure of mass. The two measure different things and, according to basic principles of dimensional analysis, conversion from one to the other is not valid.
