One hundred pence make one pound: divide pence by 100 for pounds, multiply pounds by 100 for pence. An item priced at 2,500p costs Β£25.00. It is trivial arithmetic that still causes real till errors and spreadsheet mistakes, because pence and pounds look alike until the decimal point lands wrong.
How to Use This Calculator
Pick the direction, enter the amount, and read the converted figure. The calculator formats pounds to two decimals and pence as whole numbers, matching how each is actually written.
Choose pence to pounds or pounds to pence.
Enter the amount. Whole pence only on the pounds-to-pence side: fractional pence do not exist in cash.

The Pence to Pounds Formula
Decimalisation in 1971 replaced 240 old pence per pound with 100 new pence, which is why the math is clean. Prices in pence are integers by convention; pounds carry two decimals. Mixing the two without converting is the classic error: 2500 entered as pounds instead of pence turns a Β£25 item into Β£2,500.
Worked Example
A supplier quotes 2,500p per unit. In pounds that is 2,500 / 100 = Β£25.00. For 40 units the order totals Β£1,000. Reverse: a Β£1,000 budget is 100,000p, so at 2,500p per unit you can buy exactly 40 units. The integer check on the pence side catches rounding errors before they reach an invoice.
Reading Your Result
Always sanity-check the magnitude: if the answer looks 100 times too big or small, the units got mixed. In spreadsheets, keep one column for pence (integers) and one for pounds (decimals), never both in one column. Label the units in the header, because the next person to open the file will not guess.
My rule: do money math in pence (integers) whenever code is involved. Floating-point decimals like 0.1 cannot be represented exactly in binary, so repeated pound arithmetic drifts by fractions of a penny. Integer pence sidestep the whole class of bug. Convert to pounds only for display, at the last step. For larger currency questions across borders, our currency converter is the next stop.
Decimalisation in 1971 was Britain's great money simplification: 240 old pence to the pound became 100 new pence overnight. Anyone handling historical prices, from archivists to novelists, still trips over the old notation of pounds, shillings, and pence. For modern conversions the rule never changes: divide pence by 100, multiply pounds by 100, and keep your units labeled.
The floating-point trap is why this calculator matters more than it looks. Storing 25.00 as a decimal in code invites errors like 0.1 + 0.2 = 0.30000000000000004, which become real billing mistakes at scale. Financial systems store pence as integers and format to pounds only for display. If you keep one habit from this page, make it that one.

Frequently Asked Questions
How many pence are in a pound?
100. One pound equals 100 pence, written Β£1 or 100p. This has been true since decimalisation in 1971 replaced the old 240-pence pound. Decimalisation Day was 15 February 1971, when Britain retired shillings and twelve-sided threepenny bits for the 100-pence pound.
How do you convert pence to pounds?
Divide by 100. 2,500p / 100 = Β£25.00. Move the decimal point two places left. The calculator above does it instantly and formats the result properly. In code, store 2500 as an integer and format as 25.00 only at display time.
How do you convert pounds to pence?
Multiply by 100. Β£25.00 x 100 = 2,500p. Move the decimal point two places right. Pence are whole numbers: there is no such thing as half a penny in circulation. Shops price in pence for items under 1 and pounds above: 75p versus 1.25.
What is the pence symbol?
A lowercase p after the number: 50p. Pounds use Β£ before the number: Β£25. In formal writing, pence amounts under Β£1 often appear as p and amounts over as Β£ with decimals. The plural of penny is pence for amounts and pennies for the coins themselves.
Why do prices end in 99p?
Psychological pricing: Β£4.99 reads as closer to Β£4 than Β£5, though the difference is a penny. It is one of retail's oldest tricks and it still works, which is why it never goes away. Charm pricing works online too: 19.99 converts better than 20.00 across decades of tests.
Do pence amounts get rounded?
Cash transactions round to the nearest penny; the penny is the smallest UK coin in circulation. Card and bank payments settle to the exact penny with no rounding needed. The UK withdrew the halfpenny in 1984: prices still end in .99, paid to the penny.
What were old pence?
Before 1971, the pound held 240 old pence (12 pence per shilling, 20 shillings per pound). Decimalisation replaced them with 100 new pence. Old coins were phased out over the following years. Pre-decimal price tags read like puzzles: 4 13s 6d meant four pounds, thirteen shillings, sixpence.
How should I store pence in a spreadsheet?
As integers in a dedicated pence column, converting to pounds only for display. This avoids floating-point rounding errors that plague decimal money math. Label columns clearly so nobody mixes units. JavaScript's 0.1 + 0.2 bug has caused real billing errors: integer pence is the standard fix.
Is 100p the same as Β£1?
Exactly. They are two notations for the same value, like 100 cents and one dollar. Use whichever fits the context: p for small amounts, Β£ for larger ones. Say 'one hundred pee' aloud: Brits pronounce the p, never 'one hundred pence' in casual speech.
Why do programmers prefer integer pence?
Because binary floating point cannot represent most decimals exactly, so 0.1 + 0.2 famously equals 0.30000000000000004. Integer pence arithmetic is exact. Financial systems store minor units as integers for this reason. Stripe, Adyen, and every payment API expect amounts in minor units: pence, not pounds.
