Each term may specify a mass and/or a volume -(separated by a space), as a number followed (without an intervening -space) by a unit (t, kg, kl or -l). Alternatively each term except the first may specify a -percentage, which is applied as a percentage change to the answer from -all the preceding terms.

You can enter the value in the box either as a percentage, or as a -fraction 1/divisor, eg 1/200 is the same as 0.5%; in each +fraction 1/divisor, eg 1/2000 is the same as 0.05%; in each case it is taken as the loss for each league of the voyage.
