Effortlessly determine acceleration, initial and final speed, or time required to reach a specified speed using our acceleration calculator. The tool supports various metrics, including meters per second, miles per hour, miles per second, kilometers per hour, kilometers per second, yards/feet per second, and knots. The results are provided in meters per second squared and standard gravity units (g). This versatile acceleration calculator accommodates various vehicles and objects, including cars, buses, trains, bikes, motorcycles, planes, ships, spacecraft, projectiles, and more, thanks to its extensive support for different units. To compute the missing variable, you only need to input three out of the four parameters: acceleration, initial speed, final speed, and time (acceleration duration). The results are consistently presented in the squared form of the input unit (e.g., km/h^2), meters per second squared (m/s^2), and standard gravity units (gn or simply g). Additionally, this calculator is equally adept at calculating deceleration. By entering a reduced value for the final speed, it can determine, for instance, the deceleration needed to bring a vehicle to a complete stop within a specified duration or the braking distance for a vehicle decelerating at a given rate.

■ Know your shift, forever. You do not work a week. You work a cycle — days, nights, off-duty, rest, and around again. A normal calendar cannot say that in one line, so you end up counting on your fingers, or screenshotting the ward roster, or asking someone. Tap out your cycle once. Say which day it started. That is the whole setup, and it takes about twenty seconds. From then on the app knows what you are on for any date — next Tuesday, the wedding in eight months, the same week two years ago. ------------------------------- ● The answer is already on screen ------------------------------- Open the app and today's shift is one huge glyph filling the display. No loading, no splash, no ad, no sign-in, no empty state. Read it from across the room, or half awake at 3am, or through the window of a moving bus. Rest days are drawn in the app's one accent colour. Scan a month and your days off jump out before you have read a single character. ------------------------------- ● Any date. Any year. ------------------------------- • Scroll the month view backwards to any past year and forwards to any future year. It does not stop, in either direction — a cycle is just arithmetic, and the app does the arithmetic. • Tap any day to blow it up to full screen. • A home-screen widget shows the same glyph, worked out on the device itself, so it stays right without a network, a background task or a notification. ------------------------------- ● Reality is messier than a cycle ------------------------------- Swapped a shift? Covering for someone? Tap the big glyph and set that one day to whatever you actually worked. The cycle keeps running underneath, untouched, and the correction stays pinned to that date forever. Tap once more to put it back. ------------------------------- ● Share a cycle in two taps ------------------------------- Your rotation turns into a short code you can send to a coworker in any messaging app. They paste it and their calendar matches yours. No server sees it, no account is created, nothing is uploaded — the code is just your pattern and its start date, written down. ------------------------------- ● Private by design ------------------------------- • Zero network code. Nothing leaves this phone, ever — check it in airplane mode. • Requests no system permissions at all: no notifications, no calendar, no contacts, no camera, no microphone, no location. • No account, no login, no sign-up. Privacy label: Data Not Collected. • Zero analytics. Zero telemetry. Zero third-party SDKs. • No ads. No subscriptions. No in-app purchases. Your work schedule says where you are and when you are not home. It should never have left your pocket in the first place. ------------------------------- ● Built to be read, not operated ------------------------------- • Every control is at least 64 × 64 pt. • Single taps only. No double-taps, no long-presses, no swipes, no hidden gestures. • Deleting is never a tap on the thing being deleted. • High-contrast type on a true-black background — a full-screen glyph at 3am uses a fraction of the light a white calendar does. • Six languages: English, Korean, Japanese, German, French, Arabic, with right-to-left layout. ------------------------------- ● Made for ------------------------------- • Nurses, carers and hospital staff on 2-shift and 3-shift rotations • Firefighters, police and paramedics on 24/48, DuPont, Panama and Pitman cycles • Factory, plant and warehouse crews on 4-team 3-shift patterns • Security, transport, hospitality — anyone whose Monday is not everyone's Monday ------------------------------- ● The Baro promise ------------------------------- Shift Calendar is part of Baro — lightweight tools that respect your data, your battery, and your time. "The tools you reach for first."
