Are the zeros in 400 significant?

Leading zeros (zeros before non-zero numbers) are not significant. For example, 0.00052 has two significant figures: 5 and 2. Trailing zeros (zeros after non-zero numbers) in a number without a decimal are generally not significant (see below for more details). For example, 400 has only one significant figure (4).

Are zeros in a measurement are significant?

How many significant figures are in 500m?

Depending on the unit of measure, zeros that are at the end (or right) of a whole number may or may not be significant. For example, 500 m measured to the 1 m gives three significant digits (5, 0, and 0), whereas 500 m measured to the 10 m gives two significant digits (5 and 0).

Is 450 a significant figure?
