Questions about this item

Will the 15-digit LCD on the 4400 show results clearly next to older desktop calculators with smaller screens?

The 4400 has a 15-digit LCD measuring 3/4 in high by 2 1/2 in wide, providing a larger viewing area than many older pocket calculators.

How can I verify the 4400 is calculating fractions and unit conversions correctly after unboxing?

Enter a known fraction such as 3/8 and press the convert key to see the decimal equivalent, then convert a measurement between U.S. and metric units to confirm both functions operate.
