Mass and spoon volume differ
The selected labels declare37g,40g and35g net food mass. A teaspoon is a volume measure. Without product-specific supported density and a defined filling method,the site cannot convert those masses into an exact number of spoons. Grinding,packing and the product form can affect a volume relationship.
Use purchase arithmetic instead
The price tool can calculate what100g of declared product would cost at the selected ticket. The stock tool can round a user-chosen matching mass target to whole packages. Neither needs to estimate a recipe amount,number of meals or days a jar will last.
A concrete stock example
For a chosen100g target with26g of the exact matching37g cumin already held,the gap is74g. Two jars add74g and bring the recorded total to100g. This is a shopping calculation,not a suggestion to use that amount or proof of a particular culinary yield.
What to do with a recipe question
Use the relevant actual recipe and product instructions separately rather than inventing a conversion here. The site does not generate mixing ratios,seasoning doses or personal dietary amounts. If the required quantity basis is unknown,the calculator refuses it instead of assuming one spoon has the same mass for every spice.
A concrete purchase record
The mass-to-spoon problem is different from a unit conversion such as1000g equalling1kg. Grams and kilograms describe the same quantity;grams and teaspoons do not. The local tool supports the declared mass denominator but refuses the unsupported volume bridge. No assumed water density or generic spice density is inserted to make the calculation appear complete.
