Indeed. In the UK, car engines have been described in litres for years. Other non-liquid things that you will find described in litres in the UK are: Car boot (trunk) volume. To see if it will contain your luggage. Luggage volume (I recently used the litre value as a key comparison when buying a rucksack for a walking holiday). Kitchen microwave cooker volume Fridge and freezer volumes Lung volume Gas and air cylinders e.g. for medicine, cooking and diving. Office containers
