The word consists of the prefix 'Kilo-' (kilo-), which means 'tausend' (thousand), and the base word 'Gramm' (gram). So one kilogram is literally one thousand grams.

When a number greater than one comes before 'Kilogramm' (kilogram), the unit is not put into the plural in German. You say 'zwei Kilogramm' (two kilograms), not 'zwei Kilogramme'. This rule applies to most units of measurement.

I'd like to buy five kilograms of potatoes, please.
In writing, especially on price tags, in recipes, or in scientific texts, 'Kilogramm' (kilogram) is almost always abbreviated as 'kg'.

'Tonne' and 'Kilogramm' can both indicate weight, so they can be confused. The difference is the size of the unit: one ton is 1,000 kilograms. 'Kilogramm' is often used in everyday life for food, luggage, or body weight. 'Tonne' is more suitable for very heavy things, for example trucks, machines, or large quantities. Also important: 'Tonne' can additionally mean a waste bin, but in this relation it is about the unit of weight.
