But don’t let that fool you into thinking it’s just a toy. Wrapped inside this joyful experience is a very powerful and capable unit converter. Read on to see why.
Packed with a Punch
Convertbot contains over 500 units spanning over 20 different categories. Yes, you read that right. Fumbling your way through 500 units sounds like a chore, right? Not with Convertbot. You can enable only the units you want to use for a completely customized converter. With our beautifully categorized views and search tools, you’ll be able to find what you need quickly as well.
Mix it Up
Ever wanted to convert to and from Feet + Inches? Or maybe Pounds + Ounces? Most unit conversion apps aren’t smart enough to understand mixed units. If you are 5ft 9inches tall, you have to convert that in your head to Feet or Inches before another unit converter can understand it. Convertbot is smart enough to understand many popular mixed units like Foot + Inches, Pounds + Ounces, Stones + Pounds, Minutes + Seconds, and many more.
Let Convertbot do the Math
No need to do the math in your head anymore before converting a unit. Just enable the calculator in Convertbot and perform basic calculations to get the converted unit result on the fly. You can even tell Convertbot how many decimal places to show before rounding.
On the Money
With over 150 different currency units, you’ll have no problem trading with almost anyone around the world. Currency rates are automatically updated every time you launch the app with the option to turn off the auto-update to save on bandwidth costs.
