| In 2025 | Same as, in 1800 |
|---|---|
| £10 | £0.08 |
| £20 | £0.17 |

What these numbers can and cannot tell you
The figures compare the price index in 1800 with 2025: the cost of the same broad basket of goods and services, averaged across each year. That is the right measure for "what would this amount be in today's money" — a wage, a price, an inheritance. It is not a measure of what any particular thing cost: housing, education, and healthcare have mostly risen faster than the average, while electronics and clothing have risen far slower or fallen. And it says nothing about exchange rates, so it cannot turn 1800 pounds into another currency.
