Timezone Offset Calculator

Convert a time from one timezone to another given the UTC offsets of both. The simplest case of timezone arithmetic — useful for cross-time-zone meetings, travel planning, and reading wall-clock times across regions.

Map Scale Calculator

Convert a distance measured on a paper or digital map to the corresponding real-world distance using the map's scale ratio. Supports common scales (1:25,000 to 1:500,000) and unit conversions between cm/in/mm on the map and km/mi/m in the real world.
