Dinner for six from a card written for four is one division. Desired servings over original servings is the factor, and you multiply one ingredient by it.
If the pan is the thing that changed, the cake pan converter uses floor area instead of headcount.
One line at a time
The page holds a single amount. Salt, then meat, then stock: each visit is one ingredient. The unit you typed is the unit you get back.
The factor is the useful line
6 divided by 4 is 1.50. You can multiply the rest of the card by 1.50 without typing every line into the box.
Worked example: 2 cups from 4 servings to 6
Original amount 2, original servings 4, desired servings 6. The scaled amount is 3.00 and the factor is 1.50. That is 3 cups if you started with cups.
\[ 2\times 6/4=3 \]
Frequently asked questions
Can I scale the whole recipe in one submit?
No. Repeat the page for each ingredient, or copy the factor and multiply the card yourself.
What if I want fewer servings?
The factor drops below 1. Two cups for 4, wanted for 2, is 1.00 cup.
Do eggs survive a factor of 1.50?
The number does. A half egg is a cook’s call: beat one egg and use half of it, or round.
Why two decimals?
So 3 cups shows as 3.00 and 1.5 shows as 1.50, and a long tail does not appear.
Does this change the pan?
No. More batter in the same pan is deeper. Pan swaps are the cake pan page.
