Bitcoin amounts / Check the unit
Convert mBTC to BTC with an exact unit calculator and examples. Learn why 1 mBTC equals 0.001 BTC, how to read wallet units and avoid amount mistakes.

Start with the quick answer ↓1 mBTC = 0.001 BTC = 100,000 satoshis. The prefix “milli” means one thousandth. To convert an amount from millibitcoins to bitcoins, divide by 1,000. To go from BTC to mBTC, multiply by 1,000.
When mBTC is used as a Bitcoin denomination, you are changing how the amount is written. You are not exchanging into another asset or moving money. The Bitcoin developer guide lists millibitcoin as 0.001 BTC and explains why the unit must accompany a payment amount.
Enter the millibitcoin amount below. The result is a fixed unit conversion, so it does not need a live Bitcoin price. Five decimal places in mBTC are enough to represent whole satoshis.
Enter an amount with up to five decimal places. Use a decimal point, without commas.
0.001 BTC
100,000 satoshis
| mBTC | BTC | Satoshis |
|---|---|---|
| 0.00001 | 0.00000001 | 1 |
| 0.1 | 0.0001 | 10,000 |
| 1 | 0.001 | 100,000 |
| 2.5 | 0.0025 | 250,000 |
| 10 | 0.01 | 1,000,000 |
| 100 | 0.1 | 10,000,000 |
| 1,000 | 1 | 100,000,000 |
On a small screen, swipe the table to see every column.
The table and calculator exclude all purchase and transaction fees. They express the same quantity in different units. For the smaller unit, our satoshi guide explains sats in more detail.
| From and to | Calculation | Example |
|---|---|---|
| mBTC to BTC | mBTC ÷ 1,000 | 7.25 mBTC ÷ 1,000 = 0.00725 BTC |
| BTC to mBTC | BTC × 1,000 | 0.012 BTC × 1,000 = 12 mBTC |
| mBTC to satoshis | mBTC × 100,000 | 0.25 mBTC × 100,000 = 25,000 sats |
On a small screen, swipe the table to see every column.
You can check a conversion by reversing it. If you calculated that 7.25 mBTC equals 0.00725 BTC, multiplying 0.00725 by 1,000 should return 7.25. This simple second check can catch an extra or missing zero.
Bitcoin.org’s FAQ explains that one Bitcoin is divisible into 100 million satoshis. That lets you check the same result using whole sats: 7.25 mBTC equals 725,000 sats, which also equals 0.00725 BTC.
A decimal point separates whole units from fractions in these examples. If your app uses a comma as a decimal separator, use the format that app expects and review its confirmation screen. Do not remove punctuation without checking what it means.
A wallet may offer BTC, mBTC or sats as a display preference. A balance of 20 mBTC and a balance of 0.02 BTC can describe the same Bitcoin. Switching the display does not create a network transaction or increase the balance.
Do not treat every asset symbol that resembles “mBTC” as a Bitcoin denomination. Token tickers can be reused. An exchange token, wrapped asset or contract with a similar name requires its own asset and network checks. The fixed 1-to-1,000 conversion here applies to millibitcoin units of native BTC.
Our Bitcoin wallet guide explains addresses and key control. If you are sending a wrapped asset, read why wrapped Bitcoin cannot be sent to an ordinary Bitcoin address before making a transfer.
The unit conversion is fixed; the dollar value is not. After converting to BTC, multiply by the relevant dollar price per BTC. A price-chart estimate and an executable purchase or sale quote can differ.
When you review a purchase, ask for both the total dollars and the BTC amount you will receive. At Crypto Dispensers, our wire-transfer service explains quote approval and delivery to your wallet. Our ACH page describes another bank-funding option. The unit conversion remains the same whichever eligible payment option you use.
If you plan to sell, compare the net dollars after charges rather than multiplying a balance by a chart price and treating that as a promised payout. Our sell-crypto page explains supported sales and USD bank payouts.
There are 1,000 millibitcoins in 1 BTC. One millibitcoin is one thousandth of a Bitcoin.
10 mBTC equals 0.01 BTC, or 1,000,000 satoshis. Its dollar value depends on the Bitcoin price and any applicable costs.
Changing the display or doing the arithmetic does not cost a network fee. Buying, selling or transferring Bitcoin can have separate charges.
No. One mBTC equals 100,000 satoshis. A satoshi is 0.00000001 BTC.
If it is native Bitcoin displayed in millibitcoins, use a compatible Bitcoin receiving address and enter the equivalent amount in the sender’s displayed unit. A separate token with a similar ticker is not covered by that answer.
Five decimal places in mBTC reach one satoshi. This calculator keeps outputs to whole satoshis for ordinary Bitcoin on-chain amounts.
