To convert temperatures from Fahrenheit to Celsius, you can use the formula:

```

°C = (°F - 32) * 5/9

```

So, to convert 120-130 degrees Fahrenheit to Celsius, we have:

```

°C = (120 - 32) * 5/9 = 48.9 - 17.8 = 31.1 - 54.4

```

Therefore, 120-130 degrees Fahrenheit is approximately 48.9-54.4 degrees Celsius.
