We need to convert 45 oz to kg.
We can use the English/Metric conversion below:
1 ounce = 28.35 grams
1 kilogram = 1,000 grams
Seeing the English/Metric conversion we need to convert first oz to g
Since 1 ounce = 28.35 grams we need to multiply this relation by 45 oz
Now, we need to convert 1275.75 g to kg
Since 1 kilogram = 1,000 grams we need to multiply this relation by 1275.75 g
Finally, 45 oz = 1.27575 kg
ANSWER:
45 oz = 1.27575 kg
