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.

Seven months ago, after 29 years of living abroad, I retired and moved back to the United States. Oregon to be exact. I still have not unpacked all my household goods. But in digging through drawers that contain hastily unpacked items, I found three priceless objects that are unavailable at stores now during the first weeks of the Corona Virus outbreak. These items were two unopened packages of a hand wipes that kill %99.9 of all bacteria, a thermometer, and bottle of hydrogen peroxide. Do now the peroxide is used to clean the thermometer. But the thermometer measures in Celsius. So is a temperature of 37 degrees C with head congestion and a cough an indication of something more than seasonal allergies or not? I don’t know yet, but I am so grateful that I still have my Units Plus app on my cell phone. And I will continue to monitor, record and use the app Units Plus app to make informed decisions about my health. Thank you Units Plus.

I’ve been using this app all the time for many years. This is the first time I ever opened it when it had ads on it, but I’m thinking, somebody’s put this good, useful app out and they gotta make a living and I’ve been using it all these years so I went ahead and paid them for a year of the premium app. If they didn’t screw it up making it complicated then my previous five star review is gonna remain in place. Also, I hope that they aren’t just now asking for a paid app because they lost funding (chainsaw-style) for putting out a genuinely useful app.

Edit: I was even more disappointed to find out today that Newtons are behind the paywall of the premium version of this app under a locked category called “Force.” My rating went from 4 to 3 stars, and I have less hope now for this app ever being what I hoped it would be when I first wrote this review.I was disappointed to find out there is no option for Newtons in the “Weight” category!I’ve been using this app for years and now that I work professionally as a mechanical engineer, Newtons are a very commonly used unit many calculations because they are the normal measure of weight where kilograms are the measure of mass (I don’t mind these being in the same category on this app though). They are THE unit for weight in the Système International d’Unités (SI or metric system). I need Newtons on this app, and my rating will become 5 stars when I get it. Thank you so much, in advance, for taking my feedback and adding Newtons to this app!
