Calculator That Calculates How Much Marijuana Do I need To last a certain amt of time

This Project is for a calculator that will help people calculate how much marijuana to buy based on their usage

So the calculation would start with the following questions being asked to accumulate the data

Do you smoke blunts or prefer joints? If Joints then each joint = .32gram of marijuana
If the answer is blunts then each blunt = 1gram of marijuana
Do you use a vape to smoke? How many times a day do you reload the vape? This would be calculated at .25 gram

When someone enters the amount of usage I would like to visually represent these amounts by showing x amount of joints blunts or vape bowls.

The user could also use all 3 of the the calculation simultaneously will need to account for both numbers or they could just use one of these and the calculator should work.

How many days do you want your stash to last based on your smoking Habits:

1 Day - amount of grams to buy
1 Week - amount of grams to buy
2 Weeks - amount of grams to buy
1Month - amount of grams to buy
A Weekend - amount of grams to buy

I want the calculator to visually represent the amount of marijuana you will need to buy using a 1gram marijuana bud for each amount and then half a bud 1/3 of a bud 1/4 of a bud to show when it is less then 1gram.

I am looking for a nice clean interface. Not exactly like this one https://wakeandbake.co/thc-dosage-calculator/ but nice and clean and user friendly like the one I am providing a link for.

This will go on my WP site I will want the code to just paste directly in to a page on the site. It could be done as a plugin but that would not be necessary at all for something like this
