How many packets of 250g pasta equals to 12 ounces?

Answer 1

1 oz ≈ 28.3 g

→ 24 oz ≈ 24 × 28.3 g ≈ 680 g

680 g ÷ 250 g/packet = 2 18/25 = 2.72 packets

A little under 2¾ packets.

------------------------------------------------------------

For cookery when converting imperial recipes to metric:

1 oz ≈ 25 g

→ 24 oz ≈ 24 × 25 g = 600 g

600 g ÷ 250 g/packet = 2 2/5 = 2.4 packets

A bit under 2½ packets.

If you have used the rest of the recipe in metric, use the latter; if you have used an imperial recipe (but can only buy 250g packets of something [spaghetti?]) use the former. In either case you will need to buy 3 packets and use two of them plus a part of the third.

Answer 2

Assuming you have an imperial recipe which requires 12 oz of pasta and have measured the rest of the recipe in lbs/oz, then:

1 oz ≈ 28.3 g

→ 12 oz ≈ 12 × 28.3 g ≈ 340 g

→ 340 g ÷ 250 g/packet = 1 9/25 packets = 1.36 packets

So you'll need just over 1⅓ packets of 250g spaghetti, and thus need to buy 2.

-------------------------------

If you have converted the rest of the recipe to metric, or have a metric recipe and are used to using 12 oz of spaghetti, then the cookery conversion of 1 oz ≈ 25 g might be more appropriate, in which case:

12 oz ≈ 12 × 25 g = 300 g

→ 300 g ÷ 250 g/packet = 1 1/5 packets = 1.2 packets.

So you'll still need to buy 2 packets, but use slightly less.

The amount of the second packet to use will depend upon how large you (and you guests) like your portion of spaghetti - using about a quarter of it will probably suffice. You can always use the hole in the spaghetti ladle to measure out the number of portions of spaghetti required - the amount of spaghetti that fits in the hole is roughly a portion.
