TetherからUS Dollarへの換算（USDT→USD）

Tether to US Dollar — live rate and guide

Tether (USDT) is a stablecoin designed to track one US dollar. In practice it can trade a fraction of a cent above or below $1, and that small gap is exactly what this page shows. It is useful for checking how closely USDT is holding its peg.

Right now 1 USDT = $0.9990 and 1 USD = 1.001051 USDT. Tether currently ranks #3 by market capitalisation ($176,839,661,125) with $17,884,762,745 traded in the last 24 hours.

How to convert USDT to USD

1. Type the amount of USDT into the first box of the calculator at the top of this page.
2. The USD value appears in the second box straight away. You can also type in the second box to convert the other way.
3. Use the amount tables to see common sizes at a glance, for example 100 USDT = $99.8950.
4. To actually exchange, pick a regulated exchange or broker that supports the pair and compare its quote with the reference rate here before you confirm.

Fees, spread and why quotes differ

The rate on this page is a market reference rate. When you trade, an exchange adds a trading fee (commonly 0.1%–0.6% on spot markets), and payment-card or bank-transfer purchases usually carry a higher spread. Withdrawal and network fees also apply. Because of this the amount you receive will normally be a little lower than the headline conversion; for large amounts, compare several venues and use limit orders where possible.

What moves the USDT/USD rate?

Crypto prices respond to market-wide sentiment, liquidity, news and regulation, and to coin-specific events such as upgrades, listings and token unlocks. The USD side also changes with foreign-exchange rates, so the same coin can move differently in different currencies. This is general information, not financial advice.
