—
Kg
📏

Roll Length from Weight

L = W / (W/1000 × μm/10⁶ × ρ)

—
Meters
🎯

Roll OD (Outer Diameter)

OD = √((4×L×μm/1000)/π + Core²)

▼

👤 About Me

Vivek Kumar

I'm a Mechanical Engineer by training, a Flexible Packaging professional by career, and an app builder by passion. After 9 years working at UFlex Limited, JPFL Films, and GLS Polyfilms, I've experienced first-hand the daily inefficiencies that slow down professionals in this industry.

That frustration became fuel. I began building tools to automate repetitive calculations, streamline quality processes, and reduce manual errors. What started as personal tools slowly grew into something worth sharing.

Beyond the industry, I love building apps that make everyday life more organised, more fun, and less stressful. VKSTech (vkstech.com) is the home for all of it.
