Rules of Thumb

Most foods have about the same density as water, and will fit the conversion tables above. Foods that float are less dense; those that sink, more dense. Here are some common approximations:

1 cu in cake = 1/10 oz

1 oz cake = 10 cu in

1 cu in bread = 1/10 oz

1 oz bread = 10 cu in

1 T flour = 1/3 oz

1 oz flour = 3 T

1 c flour = 5.3 oz

1 oz flour = 1/5 c

1 lb flour = 3 c

1 t sugar = 1/6 oz

1 T sugar = 1/2 oz

1 oz sugar = 2 T

1 c sugar = 7.5 oz

1 lb sugar = 2-1/8 c
