I would use a laboratory balance, or scale to measure 10.5g of rock salt.
mg or g
Density
Put a small amount of the salt into a smaller container
Remember the Table of Imperial weights. 16 ozs. = 1 lb 14 lbs = 1 stone 2 stones = 1 quart 4 quarts = 1 cwt (hundredweight) 20 cwt = 1 ton. To answer you question 16 ozs. = 1 lb (pound).
The reason why is that there was such a plentiful amount and they could even trade it for gold 1 lb. of salt= 1 lb of gold.
About 1.9 cups
640 g = 1.41095 lb OR 1 lb and 6.57 oz
A lb of salt contain 180,08 g sodium.
That is approximately 1.884 cups
1 BTU is the heat required to raise 1 lb of water by 1 degF
lb. is an abbreviation for pound, a unit of measure.
Ft Lbs (Foot pounds) is a measure of force; where as pounds is a measure of weight. They are not comparable.
1 yd = 3 ft. 1 ft = 0.3048 m. 1 kg = 2.2046226 lb.(the 1 ft = 0.3048 m & 1 kg = approx 2.2 lb are good ones to memorize)Use dimensional analysis:1 yd | 3 ft | .3048 m | 2.2046226 lb-------------------------------------------- = 2.01591 m / kg1 lb | 1 yd | 1 ft | 1 kgUsing the approximation of {1 kg = 2.2 lb} gives 2.01168 m/kg and is only 0.21% off.
500 pounds is 1/4 ton (US measure).
Amazon is selling a 3-lb bag at about $3 a pound, or a 12-pack of 1-lb containers at less than $2 a pound
This cannot be sensibly answered. Milliliters (mL or ml) is a measure of volume, pounds is a measure of weight or mass.
