Enter the test length (inches), the test time (seconds), and the desired time (seconds) into the Time Fuse Length Calculator. The calculator will evaluate the Time Fuse Length. 

Time Fuse Length Formula

The following formula is used to calculate the Time Fuse Length. 

DL = TL / TT * DT

Variables:

  • DL is the desired Time Fuse Length (in)
  • TL is the test length (inches) 
  • TT is the test time (seconds) 
  • DT is the desired time (seconds) 

How to Calculate Time Fuse Length?

The following steps outline how to calculate the Time Fuse Length.


  1. First, determine the test length (inches).
  2. Next, determine the test time (seconds). 
  3. Next, determine the desired time (seconds). 
  4. Next, gather the formula from above = DL = TL / TT * DT.
  5. Finally, calculate the Time Fuse Length.
  6. After inserting the variables and calculating the result, check your answer with the calculator above. 

Example Problem:

Use the following variables as an example problem to test your knowledge.

test length (inches) = 36

test time (seconds) = 180

desired time (second) = 270

DL = TL / TT * DT =  ?
