How many pounds is one gallon of uncooked rice?

1 cup of rice is 180 grams so...

180 * 4 cups = 720

720 grams in a quart

720 * 4 quarts = 2880

2880 grams in a gallon

2880 / 28 grams(ounce) = 102.85

102.85 ounces

102.85 / 16(pound) = 6.42

6.428571 pounds in a gallon of rice.

obviously this will slightly vary due to a rice grain's variable weight.
