Frame rate and edit duration
A clip's length in seconds comes from time = frames / fps, and flipping it around gives frames = time · fps. A few common rates show up over and over. 24 fps is the cinema look Hollywood has used since the sound era. 30 fps is really 29.97 fps for NTSC broadcast TV across the Americas. 60 fps covers smooth gaming, sports broadcasts and other high-refresh content, while 120 fps or higher is source footage you shoot for slow motion: play it back at 24–30 fps and you get roughly 4–5× slowdown. So 86400 frames at 24 fps works out to 3600 s, a full hour of finished film. One thing to watch is drop-frame timecode at 29.97 fps, which skips frame numbers rather than actual frames so clock time stays aligned.
Applications: editing, broadcast and streaming
Editors in Premiere Pro and DaVinci Resolve reach for this to plan how long a sequence will run. Broadcasters working in NTSC and ATSC standards lean on it too, as do streamers on Twitch and YouTube who capture gameplay at 60 fps and want a rough idea of file size and render time before committing.
FAQ
Why 23.976 fps instead of 24? It's the NTSC-compatible flavour of cinema 24 fps (24000/1001), there so film can be telecined to North American TV without the timing slowly drifting.
Does higher fps mean better quality? More fps buys you smoother motion, not more resolution per frame. Cinema sticks with 24 fps on purpose, for the motion blur signature that comes with it.
How long is 1000 frames at 30 fps? 1000 / 30 ≈ 33.33 seconds.

Constant-Rate Drying Period Time
Computes how long the constant-rate period of a tray drying run lasts, t = m_s × (X₁ − X_c) ÷ (A × N_c), that is, the mass of water to be evaporated divided by the surface evaporation rate. Moisture contents are on a dry basis, in kilograms of water per kilogram of dry solid, and N_c is the evaporation flux measured while the surface is still fully wet, in kg per square metre per hour. While this period lasts the surface behaves like an open pool and the rate does not depend on the material, only on the air; it ends at the critical moisture X_c, when internal water can no longer reach the surface as fast as it evaporates. Enter the dry solid mass, the initial and critical moisture contents, the exposed area and the constant evaporation rate.
Falling-Rate Drying Period Time
Computes the duration of the falling-rate drying period under the model where the rate drops linearly with free moisture starting at the critical moisture: t = m_s × X_c ÷ (A × N_c) × ln(X_c ÷ X₂). Moisture contents go in as free moisture on a dry basis, that is, with the equilibrium moisture already subtracted, which is why X₂ can never be zero — drying down to equilibrium would take infinite time, exactly what the logarithm says. Compared with the constant-rate period this is the expensive stretch: every kilogram of water removed costs far more time than in the previous stretch, because internal transport now sets the pace. Enter the dry solid mass, the critical moisture, the final free moisture, the exposed area and the constant rate at the critical moisture.
