The voltage on outlets in Holland is 230 volts. Hotels may also have a 110-volt or 120-volt outlet for shavers. Travelers are advised to bring along a power converter and an adapter for round two-prong plugs with side grounding contacts. 


The tap water in Holland is of excellent quality and you can drink from any tap, unless explicitly stated otherwise. Bottled water is available at all supermarkets, snack bars and kiosks.


Most Dutch households use gas for cooking, central heating and to heat water.

Weights & Measures

Holland uses the metric system and therefore uses meters as its measurement for length, liters for liquids and kilos for weight. This is different from countries that use the Imperial System. The conversions between these two systems are:

Kilometers & miles 
1 mile = 1.609 kilometers 
1 kilometer = 0.621 miles

Liters & gallons 
1 gallon = 4.546 liters 
1 liter = 0.220 gallons 

Kilos & pounds 
1 pound = 0.453 kilos 
1 kilo = 2.204 pounds
