Frequently asked questions
How do I convert metric to standard? Use the chart above — for length, multiply centimeters by 0.39 to get inches, or millimeters by 0.039. This sign keeps the common length, weight, volume, and temperature conversions in one place.
What's on the standard and metric conversion sign? The most-used conversions between the US standard (imperial) and metric systems — inches, feet, and miles; ounces and pounds; cups, quarts, and gallons; plus the Fahrenheit-to-Celsius formula.
Where does it work best? Anywhere you switch between systems — home garages and workshops, kitchens, classrooms, machine shops, and maker spaces.
Designed, printed, and hand-cut in our family-owned shop in Tomball, Texas. It hangs in seconds with two pre-drilled holes.

About Lone Star art Studio
About Lone Star art Studio
That's me (Norm Lanier) way back in 1965. I've always been a creator. I was always drawing, coloring, etc. In high school, I discovered my dad's old 35mm camera, and I was hooked. I got my degree in photography and started my creative career. I then moved my creativity to this new thing called a Macintosh computer. Others recognized my passion for creating and I worked my way up to become a Senior Graphic Designer for companies like Exxon, Compaq, and HP.
As great as these companies were to work at I wasn't creating for me. With the support of my wife, I walked away from the corporate life on my 50th birthday to work for myself and I've never looked back. Today I have a team of awesome employees that help me create products in-house with the singular vision of bringing beautiful art into people's homes. Join me on the journey. Your home deserves beautiful art.
Thanks
