• Logarithmic scaleRelated: Decade markings group values by their logarithmic distance from one another.

• ExponentRelated: Powers of ten make comparisons across vastly different scales concise.

• PowerRelated: Changing an exponent by one changes a power of ten by a factor of ten.

• Slide ruleRelated: Slide rules give significant digits but generally leave the decimal-point placement to the user.

• Powers of tenRelated: Comparing exponents quickly reveals how many decimal scales separate quantities.

• Gram per cubic centimetreRelated: The factor of 1,000 distinguishes the numerical values in the two common units.

• Approximate measureRelated: Order-of-magnitude estimates answer scale questions with deliberately limited precision.
