If you have ever worked with really large numbers, our billion to trillion converter makes it simple to switch between billions and trillions and vice versa. While we hear these terms often, they aren’t something we deal with daily, yet they are essential in finance, data analysis, and economics.

All you need to do is enter a number in either the billion or trillion field, and the conversion happens automatically.

How Many Billions Equal a Trillion?

One trillion is equivalent to 1,000 billion (1,000,000,000,000).

Key points about trillions:

• Symbols: B, bn, or bil
• Most common abbreviation: B
• One billion = 1,000,000,000

Key points about trillions:

• Symbols: T or tn
• Most common abbreviation: T
• One trillion = 1,000,000,000,000

How Many Zeros Are in a Billion and a Trillion?

Here’s a simple guide:

• Billion = 1,000,000,000 (9 zeros)
• Trillion = 1,000,000,000,000 (12 zeros)

we have displayed the larger numbers on the place value chart below. Not only will this help you to visualize them, but you can also see what number comes after a trillion.

Name	Value	Zeros
Million	1,000,000	6
Ten Million	10,000,000	7
Hundred Million	100,000,000	8
Billion	1,000,000,000	9
Ten Billion	10,000,000,000	10
Hundred Billion	100,000,000,000	11
Trillion	1,000,000,000,000	12
Ten Trillion	10,000,000,000,000	13
Hundred Trillion	100,000,000,000,000	14
Quadrillion	1,000,000,000,000,000	15

_{Tip: Every step up (ten, hundred, next unit) adds one more zero — and every new “illion” (million → billion → trillion → quadrillion) adds three zeros}

How to Convert Billion to Trillion

To convert billions to trillions, divide the number of billions by 1,000: T = B / 1000

Example:

• 5 billion = 5 ÷ 1,000 = 0.005 trillion

How to Convert Trillion to Billion

To convert trillions to billions, multiply the number of trillions by 1,000: B=T×1000

Example:

• 20 trillion = 20 × 1,000 = 20,000 billion

_{And for the reverse conversion, if you’re going from billion to trillion, you divide by 1,000.}

Conclusion

With our billion to trillion converter, you can confidently handle huge numbers, whether you’re converting billions to trillions or vice versa. It’s fast, accurate, and makes enormous numbers easy to understand.
