Computer Tools is the home for the smaller, everyday utilities on computingskill.com/ — the kind of quick math you need while you're actually using a computer, rather than while planning a PC build. Instead of hardware calculators, this section covers three practical areas: storage (how much space something takes up, how long a drive might last), internet (how long a download or transfer will take, how to convert between the units ISPs and file managers use), and display (how many pixels a screen packs in, what resolution or aspect ratio makes sense, how big a monitor needs to be for your desk).
These tools are organized into three sub-hubs, each covering one theme:
- Storage Tools — drive lifespan, endurance (TBW), free space planning, and converting between storage units like GB, TB, and TiB.
- Internet Tools — download and upload time estimates, bandwidth planning, data usage tracking, and converting between Mbps and MB/s.
- Display Tools — DPI/PPI, screen size, resolution, aspect ratio, refresh rate, and pixel density calculators.
You don’t need any hardware knowledge to use these — most people land here from a search like “how long will this download take” or “how many GB is a TB,” get their answer from the relevant calculator, and move on. If you want the full context behind a topic rather than just a number, the sub-hub pages linked below go into more detail on each category, and the individual tool pages explain exactly how each calculation works.

Frequently Asked Questions
What's the difference between Computer Tools and PC Hardware Calculators?
PC Hardware Calculators help you plan or troubleshoot a physical PC build — CPUs, GPUs, power supplies, cooling. Computer Tools cover everyday computing math that isn’t tied to buying hardware, like download times, storage unit conversions, or figuring out a monitor’s pixel density.
Do I need to know my exact internet speed to use the internet tools?
It helps to have your plan’s advertised speed or a recent speed test result, but most of the internet tools will still work with a rough estimate — you’ll just get a rough estimate back.
Are these tools free and usable without an account?
Yes, every tool in this section is free to use directly in your browser, with no sign-up required.
Which sub-hub should I start with?
Start with whichever matches your question: storage questions (drive space, SSD lifespan) go to Storage Tools, speed/transfer questions go to Internet Tools, and screen/resolution questions go to Display Tools.
