None, since there can be no conversion.
A cubit foot = 1.5 square feet is a measure of area in 2-dimensional space whereas a gallon is a measure of volumein 3-dimensional space. The two measure different things and, according to basic principles of dimensional analysis, any attempt at conversion from one to the other is fundamentally flawed.
1,468 US gallons.
300 cubic feet = 2,244.156 gallons (rounded)
To convert cubits to feet you need to multiply the origin by 1.4999999999999982
Formula: Noah cubit x 1.6916 = feet300 cubits = about 507.5 feet
1 cubit = 1.5 feet so 1 cubit feet is an area of 1.5 square feet.
1 cubit = 1.5 feet so 1 cubit foot is an area of 1.5 square feet.
1 cubit = 1.5 feet so 27 cubit feet is an area of 40.5 square feet.
You cannot convert a measure of area (square feet) to a measure of volume (gallons). Gallons is a measure of volume, or of 3 dimensions. You'd need cubic feet (not square feet) to convert it to gallons.
There are 3 cubit feet in 1 cubit yard. Although irrelevant in this context, you may wish to know that 1 cubit = 1.5 feet = 0.5 yards.
1 cubit = 1.5 frrt so 1.5 cubit feet = 2.25 square feet.
8 cubit feet = 12 square feet.
None, since there can be no conversion. A cubit = 1.5 feet so a cubit foot (= 1.5 square feet) is a measure of area in 2-dimensional space. Energy is measured in terms of BTU per unit of volume or mass, not of area. So "BTU per standard cubit fet" is a nonsense unit.
