About Degrees per minute (°/min)
Degrees per minute (°/min) measures slow angular rotation in a unit accessible without decimals. Clock hands move at well-known rates in °/min: the minute hand at 6°/min, the hour hand at 0.5°/min. Solar tracking mounts move at about 0.25°/min to follow the Sun across the sky. Slow geological rotations, antenna steering drives, and industrial rotary kilns are among systems where °/min is convenient. One degree per minute equals 1/60 of a degree per second.
A clock minute hand sweeps at exactly 6°/min. A solar panel tracker follows the Sun at ~0.25°/min. A slowly rotating cement kiln may turn at 1–5°/min.
About Megahertz (MHz)
A megahertz (MHz) equals one million hertz and covers FM radio, VHF/UHF television, and older CPU clock speeds. FM radio in most countries is allocated the 87.5–108 MHz band. Early home computers and microprocessors ran at 1–20 MHz; the original IBM PC used an 8088 at 4.77 MHz. Wi-Fi channels in the 2.4 GHz band have bandwidths of 20 or 40 MHz. Wireless standards including Bluetooth, Zigbee, and many cellular bands also operate in the low hundreds of megahertz up to a few gigahertz.
FM radio broadcasts between 87.5 and 108 MHz. The original IBM PC ran at 4.77 MHz. Many smartphone processors boost to over 3,000 MHz (3 GHz).
Degrees per minute – Frequently Asked Questions
Why does a clock minute hand move at exactly 6 degrees per minute?
A full circle is 360° and the minute hand completes it in 60 minutes: 360 ÷ 60 = 6°/min. It is one of those satisfying integer results in everyday physics. The hour hand, by contrast, moves at 0.5°/min (360° ÷ 720 minutes). At any given time, the angle between them changes at 5.5°/min — which is the key to solving those "when do the hands overlap?" puzzles.
How fast does a solar tracker panel rotate to follow the Sun?
The Sun crosses the sky at 15°/hr (360° ÷ 24 h), or 0.25°/min. A single-axis solar tracker matches this rate, adjusting continuously or in small steps throughout the day. Dual-axis trackers also compensate for the Sun's seasonal altitude change — a much slower adjustment of roughly 0.5–1° per week. The daily tracking rate of 0.25°/min is slow enough that you cannot see the panel moving.
What rotational speed in °/min do cement kilns and industrial drums operate at?
Large rotary cement kilns typically rotate at 1–5°/min (roughly 0.003–0.014 RPM). That glacial pace is intentional: raw material needs 30–60 minutes to travel the kiln's 50–100 meter length, slowly heating to 1,450°C. Faster rotation would push material through before it fully reacts. Industrial drum dryers and composting drums operate in a similar 2–10°/min range.
How do you convert degrees per minute to RPM?
Divide by 360. One full revolution is 360°, so degrees per minute ÷ 360 = RPM. The clock minute hand at 6°/min is 6/360 = 0.01667 RPM — one revolution per hour. A turntable at 33⅓ RPM is 33.33 × 360 = 12,000°/min. For rad/min, multiply °/min by π/180 ≈ 0.01745.
What °/min rate does a rotating restaurant turn at?
Most revolving restaurants complete one full rotation in 45–90 minutes, which translates to 4–8°/min. The slow rate is deliberate — fast enough that diners get a complete panoramic view during a meal, but slow enough that you do not notice the motion or feel any inertia. The famous revolving restaurant atop the BT Tower in London took about 22 minutes per revolution (16.4°/min) when it operated.
Megahertz – Frequently Asked Questions
Why did the original IBM PC run at the oddly specific speed of 4.77 MHz?
IBM needed a clock that could derive both the CPU timing and the NTSC color-burst frequency (3.579545 MHz) for the built-in composite video output. Multiplying the color-burst frequency by 4/3 gave 4.77 MHz — a convenient compromise that let one crystal oscillator serve two purposes. The weird number was pure engineering pragmatism, not performance targeting.
What is the 433 MHz band and why do so many gadgets use it?
The 433.05–434.79 MHz range is an ISM (Industrial, Scientific, Medical) band that is license-free in most of Europe. Cheap remote-control key fobs, weather stations, garage door openers, and IoT sensors all crowd into it because you can legally transmit at low power without a radio license. In the US, the equivalent unlicensed band is 315 MHz, which is why European and American car key fobs are not interchangeable.
How does FM radio achieve better sound quality than AM at a higher MHz frequency?
AM encodes audio by varying the wave's amplitude, which is vulnerable to electrical interference (lightning, motors). FM varies the frequency instead, making it inherently noise-resistant. FM also has a wider channel bandwidth (200 kHz vs. AM's 10 kHz), allowing it to carry the full 20–15,000 Hz audio spectrum in stereo. The MHz carrier frequency itself isn't what improves quality — it's the modulation method and bandwidth.
What happened to the megahertz race in CPUs during the early 2000s?
Intel and AMD marketed processors by clock speed — 500 MHz, 1 GHz, 2 GHz — implying faster was always better. By 2004, Intel's Pentium 4 hit 3.8 GHz but ran so hot and consumed so much power that performance-per-watt cratered. The industry pivoted to multi-core designs: instead of one core at 4 GHz, you got two or four cores at 2 GHz each, doing more total work with less heat. Raw megahertz stopped being a useful buying metric.
Why is Bluetooth limited to the 2,400 MHz band?
Bluetooth operates in the 2.4 GHz ISM band (2,400–2,483.5 MHz), which is reserved globally for unlicensed use. This avoids the need for regulatory approval in each country. The trade-off is sharing the band with Wi-Fi, microwaves, and baby monitors. Bluetooth mitigates interference by hopping between 79 channels 1,600 times per second — if one frequency is jammed, it has already moved on.
