How to use Meal Prep Portion Calculator
- Enter total prepared quantity, portions, quantity unit.
- Calculate, then explore portion grid, equal amounts, cumulative batch.
- Read the worked example and calculation limits before applying the result.
Worked example
1500 g shared across 5 portions = 300 g per portion.
Formula, accuracy & limitations
Quantity per portion = total prepared amount ÷ number of portions.
This does not estimate calories or convert volume into weight. Use the same chosen unit throughout.
Calculations use your inputs. Main numeric values show up to six decimal places, percentages up to two, and chart labels up to four. Time results use hours, minutes and seconds. Very small nonzero values use scientific notation.
Weigh or measure the whole prepared batch
Choose grams, kilograms or millilitres, then enter the total prepared quantity and the number of equal portions. Use the cooked batch if you want cooked portions. The tool keeps the chosen unit throughout and does not assume that a millilitre weighs a gram.
Use the result to divide the batch evenly
The main result is one portion. The portion grid illustrates equal shares, bars compare the portions, and the cumulative chart shows how repeated portions reach the whole batch. For a large batch, charts display a labelled sample rather than hundreds of tiny containers; the calculation still uses the full portion count.
Rounding does not change the original quantity
If 1000 grams is divided into three portions, the unrounded amount is one third of 1000. A kitchen scale may need whole-gram portions such as 333, 333 and 334. The calculator keeps precision internally and does not turn a displayed rounded value into a new total.
Frequently asked questions
Should I use dry weight or cooked weight?
Use the amount of the batch you plan to divide. For portions of cooked food, enter the total cooked batch. The calculator does not add water uptake, evaporation or a cooking-yield factor.
Does selecting millilitres convert the batch to grams?
The selected unit is kept throughout. A volume in millilitres is divided into millilitres per portion; no density assumption converts it into grams.
How should I divide a result such as 333.333333 grams?
The formula retains the unrounded equal share. If a kitchen scale reads whole grams, distribute the remainder in practice, such as 333, 333 and 334 grams for a 1000 gram batch split three ways.
Why are only 24 portions shown in a large grid?
A grid displays up to 24 equal portions to keep the page readable. Larger calculations still use the full entered count, and the chart labels the remaining combined quantity.
