Practical Math for Smarter Travel
Most trip-planning stress comes from unknowns — what will this cost, how long will it take, how bad will jet lag be. These tools turn each of those into a concrete estimate.
Fuel and driving costs
The Gas Mileage Calculator finds your car's real-world MPG from a fill-up, then estimates fuel cost for any trip distance. The EV Charging Cost Calculator does the electric equivalent — cost per charge and cost per mile — from your battery size and electricity rate. The Travel Time Calculator estimates trip duration from distance and average speed, or works backward to find the speed you'd need to arrive on time.
Long-haul flights
The Jet Lag Calculator estimates how many days it'll likely take to adjust based on how many time zones you're crossing and which direction, along with a few practical light-exposure tips.
Packing
The Packing List Generator loads a preset checklist based on your trip type — beach, business, camping, winter — and lets you check items off and add your own, saved privately so it's there when you start packing.
