Gauss to Nanoteslas examples

1 G

1 G × 100,000 = 100,000 nT.

10 G

10 G × 100,000 = 1,000,000 nT.

100 G

100 G × 100,000 = 10,000,000 nT.

Gauss compared with Nanoteslas

One G is 100,000 times as large as one nT, so your number gets bigger when you convert gauss to nanoteslas and smaller when you convert back. If the answer is not larger than what you typed, you divided instead of multiplying.

About gauss and nanoteslas

Gauss (G): The gauss, exactly 1×10⁻⁴ T. Nanotesla (nT): Nanotesla, 1×10⁻⁹ T.

How to calculate Gauss to Nanoteslas step by step

  1. Enter the value in G (the starting unit).
  2. Multiply by 100,000, because 1 G = 100,000 nT.
  3. The product is the value in nT. To go back, divide by 100,000 or multiply by 0.00001.

Common mistakes when calculating Gauss to Nanoteslas

  • Confusing flux density (T) with field strength (A/m).
  • Dividing when you should multiply: from G to nT multiply by 100,000; from nT to G divide by 100,000.

Gauss to Nanoteslas FAQ

How many nT are in 1 G?

1 G equals 100,000 nT.

How many G are in 1 nT?

1 nT equals 0.00001 G.

Is 1 G = 100,000 nT an exact conversion?

The factor is shown rounded to 7 significant figures (100,000). The calculator above uses more digits.

What is a nanotesla (nT)?

Nanotesla, 1×10⁻⁹ T.

How can I estimate gauss to nanoteslas in my head?

One G is 100,000 times as large as one nT, so your number gets bigger when you convert gauss to nanoteslas and smaller when you convert back. If the answer is not larger than what you typed, you divided instead of multiplying.

What is 7 G in nanoteslas?

7 G = 700,000 nT (since 7 × 100,000).

What is 40 G in nanoteslas?

40 G = 4,000,000 nT (since 40 × 100,000).

What is 200 G in nanoteslas?

200 G = 20,000,000 nT (since 200 × 100,000).

How many decimals should I keep when converting G to nT?

Match the precision of your original measurement. For example, 1,000,000 nT rounds to 1,000,000 nT at 3 significant figures; keep more digits only for engineering or scientific work.
