Eight Hundred and Thirty in Numbers

How to write 830 in words

The number 830 is written “eight hundred and thirty” in British English. Notice the word “and”: British English places it between the hundreds and the rest of the group. American English usually leaves it out.

Because 830 is below one thousand it is a single group: name the hundreds, add "and", then name the remaining tens and units. That gives “eight hundred and thirty”.

In running text the number is normally lowercase: “the fee is eight hundred and thirty pounds”. At the start of a sentence, in a heading, or on a legal document it takes capitals: Eight Hundred and Thirty. Formal documents often give both forms together, for example “eight hundred and thirty (830)”, so that a reader can check one against the other.

How to write 830 on a cheque

Banks read the amount in words as the legal amount, so it must be exact. Write the pounds in words, add the word pounds, and finish with only so that nothing can be added afterwards.

• With pence: add the pence after the pounds – “Eight hundred and thirty pounds and fifty pence only” for £830.50 – or write the pence as a fraction, “Eight hundred and thirty pounds 50/100”.
• US check: “Eight hundred thirty and 00/100 dollars”. American cheques drop the “and” after the hundreds and put it before the cents.
• Bangladesh, India and Pakistan: the currency word comes first and the amount is counted in lakh and crore – “Taka eight hundred and thirty only”, with the figure written Tk. 830/=.

830 in British and American English

This is one of the numbers where the two spellings differ. British English keeps “and” after the hundreds; American English generally drops it.

Both are correct in their own country and both are understood everywhere. For a UK cheque, contract or exam, use the British form. See British vs American English numbers for the full comparison.

830 in Bangla (বাংলায় ৮৩০)

In Bangla, 830 is written ৮৩০ using Bengali digits, and in words it is আটশো ত্রিশ. Bangla has its own word for every number from one to ninety-nine, and above that it counts in হাজার (thousand), লাখ (lakh) and কোটি (crore), the same grouping used across Bangladesh and India.

On a cheque or invoice written in Bangla the amount reads আটশো ত্রিশ টাকা মাত্র (“আটশো ত্রিশ taka only”). In English on the same cheque it is Taka eight hundred and thirty only – see How to write a cheque in Bangladesh.

Common mistakes when writing 830

• Dropping “and”. eight hundred thirty is American usage. In British English write eight hundred and thirty.
• Pluralising the group words. It is hundred, never “hundreds”, “thousands” or “millions” after a number.
• Mixing words and figures. In running text keep to one style: eight hundred and thirty or 830, not 830 (eight hundred and thirty) unless it is a legal document.
