Crypto units converter
Switch between BTC, satoshis and USDT so a number like 0.00035 BTC actually means something at a glance, instead of needing a separate app just to see what it is worth.

1 BTC = 100,000,000 satoshis, a fixed unit definition — no live price needed for this pair.

The BTC/USDT price comes live from CoinGecko and assumes 1 USDT ≈ 1 US dollar, the common approximation — not a guarantee that USDT is pegged exactly to the dollar at every second.

Why satoshis exist
Bitcoin's price per coin is now high enough that most real transactions involve a small fraction of one, which reads awkwardly as a long string of decimals. Satoshis give that same amount a whole number instead, the way describing a purchase in cents rather than a decimal fraction of a dollar can be easier to reason about.
The USDT approximation, and why it is fine most of the time
Treating 1 USDT as 1 US dollar is accurate enough for everyday planning, since it typically trades within a fraction of a cent of that mark. It is worth knowing it is an approximation rather than a hard rule, especially if you are converting a large amount where even a small deviation adds up.
When each unit is the useful one
BTC is the unit exchanges and wallets usually display by default. Satoshis make more sense when comparing very small amounts, like transaction fees or micro-purchases. USDT is the one to reach for when you actually want to picture what an amount is worth right now, in a currency that does not swing around as much day to day.
Units and conversions, the short answers
How many satoshis are in 1 BTC?
100,000,000. A satoshi is the smallest unit Bitcoin can be divided into, the same way a cent is the smallest unit of a dollar, just with more zeros.
Is 1 USDT always worth exactly 1 US dollar?
Not exactly at every moment — it is designed to track the dollar closely and usually trades within a fraction of a cent of it, but it is a market-traded asset, not a guaranteed one-to-one peg.
Why does converting to USDT need an internet connection but BTC to satoshis doesn't?
BTC and satoshis are two ways of naming the same fixed unit, so no price is involved. USDT crosses into a different asset entirely, which needs a live market price to convert accurately.
