Horsepower vs watts explained: what each power unit measures, the standard 745.7 watt conversion, and where cars use hp while watts cover the rest.

BTU explained: what a British thermal unit measures, how it converts to joules and watts, and typical BTU per hour ranges for heating and cooling gear.

A kWh (kilowatt-hour) is a unit of energy equal to a 1,000-watt device running for one full hour. See the formula, kWh = kW x hours, with worked examples.

Bandwidth vs speed explained simply: bandwidth is a connection’s maximum capacity, while speed is the actual data rate you experience day to day.

Learn how to estimate file download time from file size and connection speed, with a step-by-step formula, a worked example, and real unit tips.

Data storage units KB, MB, GB, and TB explained clearly, covering decimal vs binary counting and why a drive shows less space than the label promises.

A bit is one 0 or 1. A byte is a group of 8 bits. See why network speeds use bits (Mbps) but file sizes use bytes (MB), plus a worked conversion example.

Expected value explained simply: the formula, a fair-die example, and a coin-flip example. See why EV is a long-run average, not a guaranteed outcome.
