According to legend, during the construction of the Tower of Babel people from all over the world spoke the same language. God, deciding to moderate people’s ambitions, mixed languages, and as a result, the builders ceased to understand each other. In different countries, they not only speak different languages but also use different measures of length, weight and even different standards for outlets. Going on a trip, it is better to know in advance how to charge the phone there and what to wear at thirty degrees Fahrenheit – a down jacket or a Hawaiian shirt and shorts.
Let’s start with the main thing – from sockets.
The first thing you need to know about stress. Two international standards are accepted: one with a voltage of 100-127 V at 60 Hz, the other 220-240 V at 50 Hz. The first operates in Japan, the USA, Canada, Taiwan, as well as the Philippines and the Republic of Palau. Sockets in other regions operate at a voltage of 220-240 V. Most modern power supplies and chargers are universal and can work on both standards. Previously, there was a risk of burning the charge, but now this will not happen. However, just in case, it is better to check with the hotel if the necessary adapters and chargers are available. Not the fact that they will be in every hotel, but some hotels provide guests with these devices.
Types A and B, respectively:
There are many types of outlets – from A to M in alphabetical order. Plugs A and B are designed to operate with a voltage of 100-127 V, such are used in Japan and America. They differ only in the presence of grounding of type B. The plug has two flat contacts with round holes at the ends. The grounding pin is located below. All other sockets are designed for voltage 220-240 V. Socket format C is found in Europe and the CIS countries. These are two ordinary contacts with a thickness of 4 mm, grounding is not provided.

Also in these countries, a more massive F standard plug called Schuko is common. Above and below it has spots of contacts for grounding. Worst of all, the F-pin pins are thicker than the C – 4.8 mm versus four exactly. Because of this, it is not always possible to connect such a plug to a standard type C outlet, and if it works, then you will have to get it with great effort. If you connect the C-plug to a socket under standard F, the connection will be unreliable – the plug may simply fall out of the socket because its contacts are too small.
D-type sockets were previously popular in the UK, and now they are found mainly in the eastern countries – India, Sri Lanka, Namibia. It has three circular contacts that form the shape of a triangle. Its more modern and powerful version is socket M (adopted in South Africa, Swaziland, and Lesotho). The contact pattern is the same, but the pins are thicker.
In some European (Poland, Belgium, France) and African (Djibouti, Cameroon, and others) countries, standard E is adopted – a grounding pin comes out of these outlets. Sockets of the hybrid format F / E have a hole for it. In fact, the F / E socket is a regular F-plug, but with a socket for grounding the E-socket.
Three-pin sockets (type G) are used in the UK, Malta, Singapore, Hong Kong, and several other countries. Usually, a fuse is built into these outlets. Type H sockets are perhaps the least common: they are used in Israel and the Gaza Strip. The spot is triangular, there are sockets with flat and round contacts.
A format I outlet is common in Australia, New Zealand, Argentina, and Papua New Guinea. Three pins are flat, form the letter V. Switzerland has its own standard of sockets, it is designated as J. The format is similar to the usual type C but has a grounding pin, and the contacts are not isolated in the base area. The same type of outlets is found in Jordan, Liechtenstein, Rwanda, and the Maldives.
The Danish standard K is “E vice versa”: not a pin, but a recess is assigned to ground in this outlet. The ground contact comes out of the plug itself. Such outlets can be seen in the Faroe Islands, in Guinea, Denmark, Greenland, and several other countries.
The L format, adopted in Italy, looks like standard C with a grounding pin between the contacts. Type C plugs fit into L-type sockets at 10A, but not 16A – in the latter case, the thickness of the pins is greater. Sockets of the L-standard are in Libya, Syria, Uruguay, Chile, Ethiopia and a couple of other states.
In most countries, there are sockets of several formats at once, in addition, some sockets are adapted to a couple of standards. The main thing is to make sure that the device can operate on two types of voltage, and the adapter for the desired socket can be found without problems.
The vast majority of countries use the Celsius scale to indicate temperature. But the United States, the Bahamas, Belize, Palau, and the Cayman Islands have chosen the Fahrenheit scale. Its values are very different from Celsius. Zero Fahrenheit is about -18 Celsius, while zero Celsius is 32 degrees Fahrenheit. The temperature of the human body (+36.6 Celsius) is 97.8 degrees Fahrenheit.
Measures of weight, length, and volume
In the USA, Great Britain, and several other countries, the English system of measures is used: length in feet and miles, weight in pounds, volume in gallons. You can get confused at first, but if you sacrifice accuracy a bit, for simplicity it will be: one pound – half a kilogram, one meter – three feet, one liter – a quarter gallon, one yard – almost one meter, and one mile – a little more than one and a half kilometers . Exact parameters: 1 liter – 0.26 gallons; 1 meter – 3.28 feet; 1 pound – 0.45 kg; 1 yard – 0.9 meters; 1 mile – 1.6 kilometers. By the way, the United States has its own system for calculating fuel consumption in a car. If you intend to travel by car, the consumption figures when choosing a rental car can be stupid: Americans do not consider liters per hundred kilometers, but the number of miles that the car will travel on one gallon of gasoline (MPG). So, 20 mpg corresponds to 11.7 liters per 100 km, and 30 mpg is 7.8 liters per 100 km. The higher the number, the lower the fuel consumption of the car.
