It does EXACTLY what it says, and that’s AWESOME!

Like most people in the US, the metric system, to me, is a mystery. I used to work in international sales and can’t overstate how important it is to get an understanding of the metric system. This is especially true when taking custom-made product orders which require precise measurements of size, weight & length. International customers almost exclusively use and provide measurements in metric. This app makes those conversions from Imperial to Metric and vice versa, quickly and efficiently.

On another note, for culinary situations, I personally use metric. It’s much more precise, which is essential dealing with liquids and especially for baking. It is infinitely easier to convert baking recipes from cups, ounces and pounds entirely to metric units with this app. My baking results went through the roof once I started metric units. This app even does temperatures from Fahrenheit to Celsius.

I use this app every day, get it.

Awesome App, I can’t thank you enough! 👍🤠

Since the very first iPhone came out on the very first day! I’ve been using the iPhone and one of the Apps I wanted was a App that converted all the many different Units, an App that didn’t require a PHD to use! I’m sure over the years I’ve tried hundreds of different ones! And I keep returning to this App! It’s easy enough that I have no problem using it! I have yet to try the “Pro” Version and may one day if for no other reason than to thank the people behind this App for their great work! Without any question this is a “Five Star App” !!!! 👍🤠👍🤗

Great App for Everything... EVERYWHERE!!!

We have travelled to 26 countries and this app has been our “best friend” for quickly figuring out all kinds of conversions for all kinds of currency.

Icelandic Kronos, Chinese Yuan (RMB), Japanese Yen, Euros, you name it...

We also like to stay at Air BnBs.... so this app has also been very helpful for doing metric conversions for making dishes and figuring out what we need to buy.

Lastly... temperature from Celsius to Fahrenheit has been a lifesaver when setting the thermostat to a comfortable level and dressing appropriately for the outside weather.

One quick tip I learned that has been a great “manual” converter for temperature...
Multiply the Celsius number x 2
Then add 32
So 20 degrees Celsius becomes
40+32=72 degrees Fahrenheit

Other than that trick we always stick to the app and are very happy and confident wherever we go.

Hope this makes your life and your travels easier.
