This USD to GBP calculator shows the mid-market rate — the exact midpoint between the buy and sell price on the wholesale foreign-exchange market. It is the rate banks trade at with each other, and the fairest benchmark for what a currency is genuinely worth right now. No consumer bank, card or transfer service passes on the mid-market rate for free — each adds its own margin, which is how they make money on the conversion.
That means the number this calculadora shows and the number that lands in your account after a bank transfer or card payment will always differ slightly. The gap is the provider's margin, not an error.
Converting USD to GBP by hand
The maths is one multiplication: dollars × rate = pounds. Divide instead of multiply to go the other way.
USD to GBP
At a mid-market rate of 0.79: $100 × 0.79 = £79. $500 × 0.79 = £395. $1,000 × 0.79 = £790.
GBP to USD (the reverse)
Divide pounds by the rate instead: £100 ÷ 0.79 ≈ $126.58. Equivalently, multiply by the inverse rate (1 ÷ 0.79 ≈ 1.2658): £100 × 1.2658 ≈ $126.58. Toggle the direction above to convert pounds to dollars directly.

Why your bank quotes a different number
Three things separate the mid-market rate from the amount you actually get:
FX margin — the provider's spread on top of mid-market, typically 1–4% at a high-street bank, often under 1% at specialist transfer services.
Flat transfer fees — a fixed charge per transaction, on top of the margin, more common on smaller transfers.
Card network fees — a separate non-sterling transaction fee some cards charge regardless of the exchange rate used.

Currency conversions rarely stop at USD/GBP. These companion calculadoras cover the routes we get asked about most:
Why is my bank's USD to GBP rate different from this one?+
This page shows the mid-market rate — the real, no-markup exchange rate banks trade at with each other. Your bank, card provider or money-transfer app adds a margin on top (often 1–4%), which is how they profit on the conversion. Specialist transfer services usually charge a smaller margin than high-street banks.
Is now a good time to convert USD to GBP?+
Nobody can reliably time currency markets, but the 30-day chart on this page shows whether the current rate sits near the recent high or low — useful context if you have flexibility on when to convert, even though past movement does not predict future direction.
What is the difference between the mid-market rate and the rate I get?+
The mid-market rate is the wholesale benchmark. The rate you are actually offered subtracts the provider's margin and any flat fee. On a £1,000 transfer, a 3% margin costs about £30 more than converting at the true mid-market rate.
How do I convert pounds to dollars?+
Divide the pound amount by the USD/GBP rate, or multiply by its inverse. At a rate of 0.79, £100 ÷ 0.79 ≈ $126.58. Use the toggle above to switch the conversion direction.
How much is $100 in pounds?+
At the current mid-market rate shown above, multiply 100 by the rate — for example, at 0.79 that's £79. Your bank will likely quote slightly less after its margin.
Is USD to GBP the same rate everywhere?+
The mid-market rate is universal at any given moment — it's set by the wholesale FX market. What differs between providers is the margin added on top, which is why the same conversion can cost more at one bank than another.
How often does the USD/GBP rate change?+
Continuously during market trading hours — the rate shown here updates in real time. It moves in response to economic data, interest-rate decisions and overall market sentiment.
What affects the USD to GBP exchange rate?+
Mainly interest-rate differentials between the Bank of England and the Federal Reserve, relative economic growth, inflation data and risk sentiment — periods of market stress typically strengthen the dollar against the pound.
