Dec2Frac!
Dec2Frac converts decimal values into fractions while allowing the user
to decide how precise the conversion should be. Handy for converting
measurements in the kitchen, workshop, garage, science lab, and more.
Not only does it convert decimals to fractions, it reduces the fractions
using the Euclidean algorithm. It also returns whether the fraction
result is smaller, equal to, or greater than the decimal entered. Very
handy to know if selecting drill bits.
For example, you need to decide what size drill bit to use for a wooden
dowel. Your calipers measure the dowel to be .6424". Your drill index is
based on 1/16" drill bits. This calculator returns the value of 5/8" and
tells you that the result is smaller than your decimal. This means that
a 5/8" drill bit is the closest fit, but you might need to go up one
size since the result was smaller than your decimal measurement. You
decide you want to be more accurate, so you pick up a drill bit set that
is indexed by 1/32". Using a precision value of 1/32", the calculator
returns the value of 21/32" and also tells you that the result is larger
than than decimal measurement. So choosing a 21/32" drill bit will give
you the closest size to your dowel and is slightly larger than your
measurement so the fit should be just right.
As a learning tool, students can explore the complexities of converting
decimals to fractions while introducing them to the concept of
precision.
Includes an Apple Watch App with option to enter decimal from keypad on
watch or by dictation.
