Ratings and ReviewsSee All
Yes!!!!Finally!!!! It just simply does what you need it to do!!!
It is ridiculous how much time I spent trying to convert ft/lb to Nm! Should be simple, just look it up! Right! So many unit conversion apps but none of the ones I had would do this simple function. Until I found this one! It was so freaking fast!!
Quicker than doing the math
I have friends and a daughter living in France and Australia, and when we discuss the weather, I can find my temperature in Celsius or learn theirs in Fahrenheit in about 10 seconds while on a video chat.
Most excellent app!!!! Please add speed conversion!!! Miles per hour, kilometers per hour, feet per second, knots, etc...... Thank you so much for offering your wonderful and user friendly app!!!!!
