GBP to USD Converter
Start with the pound sterling amount you want to convert.
Buying from a UK shop, splitting a London hotel invoice with a US friend or pricing a freelance quote — every case needs the same number, pounds sterling in US dollars. This converter applies the current GBP/USD mid-market rate and shows how much margin a typical bank card, PayPal or Wise transfer adds on top.
How the conversion works
-
1
Enter the amount in GBP
Decimal values are fine, including amounts below £1.
-
2
Multiply by the GBP/USD rate
The tool uses the published mid-market rate (also called the interbank rate).
-
3
Read the USD amount
The converted value appears alongside a comparison of typical card margins.
Formula
USD = GBP × GBP/USD rate
The GBP/USD rate (known as “cable”) is quoted to four decimals and moves every few seconds during market hours. A £100 transfer at 1.2650 is $126.50 at the mid-market rate — before any fee.
Where banks take their cut
| Channel | Typical margin vs mid-market |
|---|---|
| High-street bank (card abroad) | 2.5–4.0% |
| Currency exchange at the airport | 8–12% |
| PayPal (cross-currency) | 3–4% |
| Revolut / Wise / Monzo (weekday) | 0.3–0.5% |
| Interbank / mid-market | 0% (reference only) |
A £500 hotel bill paid with a high-street card at 3% margin costs roughly $16 more than the mid-market figure — significant on trips or recurring subscriptions.
Historic context
- Lowest modern GBP/USD: ~1.0350 in September 2022 after the UK mini-budget.
- Bretton Woods peg: 2.80 from 1949 until 1967.
- Long-term average (since free float, 1971): around 1.65.
Rates are volatile — locking large amounts with a forward contract is worth it if a payment is more than a couple of weeks away.
