Cheese, cold meats, olives, pickles etc will be priced pr kg or pr 100 g

Problems can arise when a younger counter assistant (educated in metric) serves an older consumer (educated in imperial). A useful hint to ensure you receive the same amount of cheese or cold cuts is to ask the assistant for the nearest metric unit and remember that next time.

Here is a useful guide:

If you usually buy Ask for
1/4 lb (4 oz) 100 g - 125 g
6 oz 150 g - 180 g
1/2 lb (8 oz) 250 g
1 lb 500 g (1/2 kg)

Packaged Foods



Most of these are sold in metric units of

30/50/100 g – crisps and snacks
150-180 g – yogurts
200 g – crème fraiche
250 g – butter, fat spreads, cheeses
400 g – breads, speciality sausages
500 g – sugar, flour
1 kg – sugar, flour

Exceptions

Due to anomalies in the UK law certain ‘soft’ or direct conversions are permitted on labels leading to awkward amounts   e.g.
454 g (1 lb) – sausages, frozen peas, strawberries
568 ml – 1 pint of milk or cream.



Liquids

The basic unit of volume is a litre (l) There are 1,000 millilitres (ml) in a litre. Divisions of a litre are marked in millilitres (ml), centilitres (cl) or decilitres (dl)
As most liquids are sold bottled or canned, shoppers will buy 1, 2 or 3 litre bottles / wine boxes

The usual bottle sizes on sale are
150 ml (e.g. Worcestershire sauce)
250 ml / 25 cl (soy sauce, some vinegars)
350 ml / 35 cl (half bottle whisky)
500 ml / 50 cl ( vinegars, oils, beer in bottles)
750 ml / 75 cl (wine)

Unit Pricing
