Enter the known values in the units shown. Results update as you type.
Where results are editable, change one to solve backwards. Lock a value to hold it fixed.
Use the worked example to check the method. Reset restores the starting fields.

Inputs and results stay in this browser tab. Bookify does not upload or store the values you enter.

150 minutes equals 2.5 decimal hours or 9000 seconds.

Total seconds = 3600h + 60m + s; decimal hours = total seconds/3600.

Enter these known values and leave the other values blank.

The three inputs are duration components, not a clock time or timezone. Values are added without calendar or daylight-saving adjustments.
Hours and seconds components are retained hidden source controls fixed initially at zero; the visible input is minutes. Component outputs are internal relationships; the three totals are derived displays.
Clear the value you want to solve before entering the remaining independent measurements. Display rounding does not describe measurement uncertainty.

Leave the unknown field empty. Supply enough independent values; lock a known value if you need to preserve it while changing another control.

Enforce the stated arithmetic and physical domains.
