# to weigh or to weight

I am a bit confused regarding what is the correct way to say that we adjust a value according to some factor.

What is the correct way to write the following sentence:

A number between 0-1 indicates how to weight the value when calculating the final score.

or

A number between 0-1 indicates how to weigh the value when calculating the final score.

• If you're thinking in terms of calculating a "weighted average", then "weight" is the word to use. If you're thinking in terms of judging the values (for how accurate they are or whether they're worthy of inclusion in whatever you're doing, for example), then "weigh" is the word to use. – tautophile Jul 9 '18 at 22:31
• In the case of this sentence, weight is the only word that makes sense. Weigh in this context simply means 'think about', and a number between 0 and 1 does not indicate anything about how to do that. Whereas such a number is useful as a weighting factor. – John Lawler Jul 9 '18 at 22:48
• The train car was weighed by a scale under the track. The car was weighted by a load of coal. – Hot Licks Jul 9 '18 at 23:00
• I can see both weigh and weight being applicable here, but unless you tell us what you're trying to say in other words, it is impossible for us to know which meaning is intended: to weigh (to determine how heavy or important something is) or to weight (to assign a level of heaviness or importance to something). – choster Jul 9 '18 at 23:10
