Using water weight to calculate volume
I want to precisely calculate the volume of a bread pan. If the pan is placed on a scale and tared, then filled with water, can this be used to determine volume?
Let’s say the water weight needed to fill a pan is 1000g. We know that is 1000ml.
Is 1000ml equal to 61.0237 cubic inches?
I want to be sure I understand this correctly.
Thanks in Advance,
Danny

1,000 mL = 1,000 cubic centimeters = 61.0237 cubic inches
Depending on how precise you want to be... Make sure you're using cold water in your weight measurement. Warm water has a density less than 1 g/mL.
I'd say water temperature (as long as it's liquid) affects density negligibly for everyday measurements, and the error will be less than 5% even when it's at the boiling point https://www.usgs.gov/special-topic/water-science-school/science/water-density?qt-science_center_objects=0#qt-science_center_objects
Ilya, I agree. For any temps we’re using in baking, approximating with 1 g/mL is usually close enough.
I definitely agree.
Staying in metric is so much easier since 1 mL of water occupies 1 cubic cm of space. So if a pan holds 1000 g of water, it would take 1000 mL of water and be 1000 cm3 in volume.
So my pullman pan is 9x4x4 inches. 22.86x10.16x10.16 cm = 2360 mL liquid volume = 2360 cm3 spatial volume and take 2360 g of water in weight.
