Calculate Price per Weight (Mass)

Extrapolate a price for a weight or mass to the price for another weight or mass. The term weight is used colloquially for mass. As units, milligrams (mg), grams (g), kilograms (kg) and tons (t) can be used.
Please enter two values in one row, the values of the other row will be calculated. The price is rounded to two decimal places.

Example: if 100 grams cost 1.50 €, then 2.5 kilograms cost 37.50 €.

Food and raw materials are often sold by weight or mass. In the case of food, this is usually unprocessed and natural, such as fruit and vegetables, cheese, fish and meat. Sometimes these can be weighed precisely, so you can easily buy 200 grams of sliced cheese, for example. This is not possible with other foods that are a certain size. Exactly 200 grams of apples will rarely work, as apples are generally only sold whole. Raw materials such as metals (for example gold) are also sold by mass and can be weighed very precisely. Liquids, on the other hand, are often sold by volume and not by mass, the information is then in liters, for example, but the extrapolation to other quantities works just as well.
Sometimes there is a volume discount for purchasing large quantities, but this is of course not taken into account in an extrapolation.

Weight and mass are used synonymously here, as is common and widespread in colloquial language. Physically, this is not correct, but since the conversion between the two depends on the gravity of the place where you are, and in most cases we are on Earth, this incorrect use is not misleading. The unit for weight is the newton and for mass the kilogram; on the Earth's surface, a kilogram corresponds on average to a force of approximately 9.81 newtons, with very slight variations depending on the exact location on the Earth's surface.
