1 oz$ = \frac{1}{16}$ lb

1 oz$= \frac{1}{16}$ lb To convert ounces to pounds, divide the weight in ounces by 16.Weight in ounce $\times \frac{1}{16} =$ Weight in pounds |

1 lb $= 16$ ozTo convert pounds to ounces, multiply the weight in pounds by 16.Weight in pounds $\times \frac{1}{6} =$ Weight in ounce |

**How to Convert Ounces to Tons**

1 pound $= 16$ ounces

Thus, 2000 pounds $= 16 \times 2000 = 32000$ ounces

but 2000 pounds $= 1$ ton

Thus, 1 ton $= 32000$ ounces

1 lb $= \frac{1}{32,000}\;t$To convert ounces to tons, divide the weight in ounces by 32000.Weight in ounce $\times \frac{1}{32000} =$ Weight in pounds |

1 t $= 32,000$ lb To convert tons to ounces, multiply the weight in tons by 32000.Weight in pounds $\times 32000 =$ Weight in ounce |

## Ounce and Gram

1 ounce is approximately equal to 28.3495 grams.

1 oz $= 28.35$ g
