sen

A sen is a small unit of money worth one-hundredth of a larger currency in some Asian money systems. It works much like a cent does in dollars: it names the tiny part that makes up a whole unit.

The word comes from Japanese (銭), where it originally referred to a coin. In modern English, you may see it when people talk about money in places like Indonesia or Malaysia, and also in older writing about Japan, where it once meant 1/100 of a yen. Think of it as the kind of small unit that matters in prices, accounting, and exchange rates, even when people do not handle it much in daily life.

The word sen refers to a fractional monetary unit used in several Asian countries. It represents one-hundredth of the main currency unit, similar to how a cent is one-hundredth of a dollar.

In Japan, where the term came from, a sen was 1/100 of a yen. That Japanese use is now historical rather than current, so today you are more likely to meet the word in history, older documents, or explanations of past prices. In other places, especially Indonesia and Malaysia, the word is still used for 1/100 of the main currency, even if the smallest amounts do not matter much in ordinary cash use.

You might encounter sen when dealing with exact prices, bank records, exchange rates, or historical texts. For example, if a price or rate includes decimals, those last two digits may be read as sen in a system that uses that unit.

In English, both sen and sens appear as plural forms, depending on the country and style guide, so it is safest to follow the local usage of the currency being discussed.

So whether you are reading about Japanese history, checking a price in Malaysia, or looking at currency figures from Indonesia, understanding that a sen is a very small part of a larger money unit helps those numbers make more sense.
