To convert a number to scientific notation, we need to move the decimal point to the right or the left until there is only one non-zero digit to the left of the decimal point. In this case, we need to move the decimal point 3 places to the right to get the number 1.61. Since we moved the decimal point to the right, we need to multiply by a negative power of 10 to compensate. The number of places we moved the decimal point is the exponent of 10. Thus, the final answer in scientific notation is $1.61 \times 10 ^ { - 3 }$.
