As we know One second is equal to 0.000308642 ^g (1 second = 0.000308642 ^g).

To convert Second to Grad, multiply your second figure by 0.000308642.

Example : convert 25 second to ^g:

25 second = 25 × 0.000308642 ^g = ^g

To convert Grad to Second, divide your ^g figure by 0.000308642.

Example : convert 25 ^g to second:

25 ^g = 25 ÷ 0.000308642 second = second
