Networking & Storage
Bandwidth Calculator
Enter file size and transfer speed to see how long a download or upload takes. The calculator handles the bits-vs-bytes conversion automatically, so your ISP's Mbps and your browser's MB/s stay comparable.
Base64 Encode / Decode
Encode text into Base64 or decode Base64 back to text, with the distinction between transport encoding and real security kept clear.
Electricity Cost Calculator
Turn appliance wattage, daily hours, and your electricity rate into daily, monthly, and annual running-cost estimates.
File Size Storage Calculator
Enter file size and number of files to get total storage required in your chosen unit. Choose between decimal (GB) and binary (GiB) standards — the same reason your 1 TB drive appears as 931 GB in Windows. Also converts any file size between all common units.
Internet Usage Calculator
Estimate monthly data use from the selected activity, daily hours, and days per month, then see how strongly that habit can affect a capped plan.
Ohm's Law Calculator
Enter two different known values to calculate the remaining electrical values and see when a zero denominator makes a result undefined.
Resistor Color Code Calculator
Choose the four color bands to read the resistor value, tolerance, and the actual range allowed by that tolerance.
Subnet Calculator
Enter an IPv4 address and CIDR prefix to get the network address, broadcast address, subnet mask, and usable host count. Change the prefix to see how splitting a /24 into /25s or /26s reduces host capacity and enables network segmentation.
URL Encode / Decode
Encode or decode URL components so spaces and reserved characters travel safely, while keeping percent-encoding separate from security controls.
Voltage Drop Calculator
Calculate voltage drop and percentage from Current (amps), Wire length, Wire gauge, with the key formulas and caveats needed to interpret the result correctly.
