He inferred g from tests of various abilities, such as vocabulary, memory, and reasoning.
yes
you will measure it in grams
g is a measure of acceleration, not of velocity (or speed).

Spearmen's theory of intelligence consisted of two factors: general (g) and specific (s). The g factor tended to include one's ability to 1) acquire and retain information from experience, 2) infer relationships between two things, and 3) infer principles to new domains.

Spearman and Thurstone both believed in the existence of a general intelligence factor, g, but differed in how they viewed how intelligence was structured. Later psychologists questioned the idea of a single general intelligence and instead proposed the existence of multiple intelligences due to evidence of different abilities across individuals.
The technique of factor analysis in intelligence testing was introduced by psychologist Charles Spearman in the early 20th century. Spearman proposed that intelligence is made up of a general factor (g) and specific factors (s) that contribute to an individual's cognitive abilities.
Early psychologists like Alfred Binet and Charles Spearman would have been most enthusiastic about the value of a single intelligence test score as an index of an individual's mental capacities. Binet developed the first intelligence test, while Spearman proposed the concept of general intelligence (g factor).

Psychologists who support the concept of general intelligence (g-factor) would be most enthusiastic about using a single intelligence test score as an index of an individual's mental capacities. They believe that this score reflects an underlying intelligence factor that influences performance on a variety of cognitive tasks.
Early theories of intelligence, such as Spearman's g-factor theory, focused on a single general intelligence factor. Contemporary theories, like Gardner's theory of multiple intelligences, propose that intelligence is composed of various abilities across different domains. While early theories emphasized cognitive abilities, contemporary views consider emotional, social, and practical intelligence as essential components of intelligence.
According to Spearman's theory, performance in intellectual tasks is determined by a general mental ability factor called "g" or general intelligence. This factor influences overall cognitive functioning and is thought to underlie performance on diverse intellectual tasks.
I personally highly disagree with this idiotic notion but everyone who takes Intelligence Quotient scores seriously takes this idea seriously. Of course nowadays when employers seek employees they look at community service and criminal records as well as test scores, depending on the requirements of the job.
