The standard voltage of electricity in Nepal is 230 V, and the frequency is 50 Hz. Suppose the standard voltage in your country is between 220 and 240 V, as is the case in the UK, Europe, Australia, and most countries in Asia and Africa. In that case, you can use your electrical or electronic equipment in Nepal without the need for a converter. However, if the standard voltage in your country is between 100 and 127 V, as is the case in the USA, Canada, and most countries in South America, you will need a voltage converter to use your devices. If you are unsure of the voltage, you can look on your device to see where you can find a label. If the label says something like "INPUT: 100-240V, 50/60 Hz", your device can be used in any country in the world. The plugs and sockets used in Nepal are type C, D, and M, usually with three small or large round pins. Type C is the standard European plug, which also works with plug E and plugs F. Type D plugs are mainly used in India, Nepal, Sri Lanka, and many African countries and only work with D plugs. Type M is the same as type D but has larger pins and only works with M plugs.
