Units of measurements
The European system of units of measurements stems from the international system of units (SI). The SI serves as a global standard and EU law makes the SI units the legal units of measurements to be used for expressing quantities in the EU.

Measuring instruments harmonised by EU law range from weighing scales, measuring tapes via petrol pumps and utility meters (gas, electricity, thermal energy, water) to taximeters and weighing bridges. EU law establishes the essential requirements that measuring instruments have to satisfy to be sold or put into use in the EU. It aims to ensure the accuracy of measurements and to help the transparency and fairness of commercial transactions.

Pre-packaged products and pack sizes
EU pre-packaging legislation defines the quantity contained in pre-packaged products. It helps guarantee the net quantity in prepacks and the volume of product in bottles or jars. EU law requires national authorities to do regular market surveillance. EU law prohibits EU countries to legislate on sizes and it lays down fixed sizes for wine and spirit drinks.
