To round to 3 significant digits, start counting from the first non-zero digit. If the digit to the right of the third significant digit is 5 or greater, round up. If the digit is less than 5, leave the third significant digit unchanged. Replace all digits to the right of the third significant digit with zeros.

No rounding is necessary; it is already displayed in six significant figures.
