How many kilos of hot dog are needed in cooking spaghetti for 60 persons?

You'll need more information to determine how many kilos of hot dog you need. Here's why:

* Serving size: How many hot dogs per person are you planning?

* Hot dog size: Are you using regular-sized hot dogs, jumbo hot dogs, or something else? The weight of each hot dog varies.

Here's a general guideline to help you estimate:

1. Decide on serving size: Most people eat 1-2 hot dogs per meal. Let's say you're aiming for 1.5 hot dogs per person.

2. Estimate hot dog weight: A regular-sized hot dog usually weighs around 50-60 grams. Let's assume 55 grams for our calculation.

3. Calculate total hot dog weight:

* 60 people * 1.5 hot dogs/person = 90 hot dogs needed

* 90 hot dogs * 0.055 kg/hot dog = 4.95 kg of hot dogs

Therefore, you would likely need around 5 kilos of hot dogs to serve 60 people.

Important Note: This is just an estimation. Adjust the number of hot dogs and hot dog weight based on your specific needs.
