Abstract
A ruler includes an elongated base having a longitudinal axis, a first outer edge, and an opposite second outer edge. A scale is received by the base and is slidably positionable along the longitudinal axis to a plurality of detent positions. The scale includes indicia depicting both fractional and decimal portions of one inch.

A ruler comprising:
- an elongated base having a longitudinal axis, a first outer edge, and an opposite second outer edge;
- a scale which is received by said base, said scale slidably positionable along said longitudinal axis to a plurality of detent positions;
- said scale including indicia depicting both fractional and decimal portions of one inch;
- said base including a first inner edge, an opposite second inner edge, a first inner end edge, an opposite second inner end edge, said first inner edge, said second inner edge, said first inner end edge, and said second inner end edge forming a longitudinal slot:
- said scale received by and longitudinally positionable along said slot;
- said first inner edge including a plurality of spaced apart first notches;
- said scale including an outwardly biased first stop which engages one of said plurality of first notches;
- said second inner edge including a plurality of spaced apart second notches;
- and,
- said scale including an outwardly biased second stop which engages one of said plurality of second notches.

A method for measuring a distance comprising:
- (a) providing a first point and a second point;
- (b) providing a ruler having an elongated base having a longitudinal axis, a first outer edge including inch indicia, an opposite second outer edge, an index mark, a scale which is received by said base, said scale slidably positionable along said longitudinal axis to a plurality of detent positions, said scale including scale indicia depicting both fractional and decimal portions of one inch, said scale including a scale index;
- (c) positioning said base so that said index mark aligns with said first point;
- (d) slidably positioning said scale until said scale indicia aligns with said second point;
- (e) using said scale index and said scale indicia to determine the distance between said first point and said second point;
- in (a) said base including a first inner edge, an opposite second inner edge, a first inner end edge, an opposite second inner end edge, said first inner edge, said second inner edge, said first inner end edge, and said second inner end edge forming a longitudinal slot, a scale received by and longitudinally positionable along said slot;
- in (a) said scale including a tab;
- in (a) said first inner edge including a first disassembly notch, and said second inner edge including an opposite second disassembly notch;
- said first and second disassembly notches shaped and dimensioned to allow passage of said tab;
- positioning said scale so that said tab aligns with said first and second disassembly notches;
- and,
- pushing said tab toward said base wherein said tab passes though said first and second disassembly notches and said scale separates from said base.
