Yes! A calculator and metal ruler are good to go in carry-on bags!
Tools that are longer than 7 inches remain prohibited, as do hammers, drills, drill bits and saws.
Edit: Looks like you can't fly with drills or drill bits in the US. I'm going to leave this post up so others know. It wasn't obvious for me but I hardly ever fly with tools. Thanks for the clarification and the link for the TSA website below.
Tools 7 inches or shorter may be allowed in carry-on baggage. Power tools and all other tools greater than 7 inches must be packed in your checked baggage. For more prohibited items, please go to the 'What Can I Bring?'
Firearms, ammunition, and fireworks are prohibited, as are all knives and safety razors (including pocket knives and Swiss Army knives). Straight razors and replacement blades for straight razors are also not allowed. Most tools also cannot be packed in carry-on luggage, as they have the potential to cause harm.
Tools 7 inches or shorter (measured from end to end when assembled) are allowed in carry-on baggage.
What happens if you have a lighter in your suitcase? If you have a lighter in your luggage, it will likely be found by the security staff at the airport security checkpoint. Depending on your airline's policy, you could be forced to leave the lighter behind before boarding or take it on board as a non-baggage item.
Each passenger is limited to one quart-size bag of liquids, gels and aerosols. Common travel items that must comply with the 3-1-1 liquids rule include toothpaste, shampoo, conditioner, mouthwash and lotion.
Lithium metal batteries: The lithium metal content must not exceed 2 g. Lithium-ion batteries: The Watt-hour rating must not exceed 100 Wh.
TSA uses millimeter wave advanced imaging technology and walk-through metal detectors to screen passengers. Millimeter wave advanced imaging technology safely screens passengers without physical contact for metallic and non-metallic threats, including weapons and explosives, which may be concealed under clothing.
The “3” in the 3-1-1 rule refers to the 3.4 ounce limit. All 3.4-ounce containers must fit into a clear one-quart bag: that's the first “1.” Only one bag is allowed per passenger (that's the last “1” in 3-1-1).
Portable electronic devices powered by lithium batteries that are placed in checked baggage must be completely switched off (not in sleep or hibernation mode) and protected to prevent unintentional activation or damage.
Not Allowed in Carry-On Luggage
Tools, such as hammers, wrenches, crow bars, nails, axes, hatchets, screws, saws, screwdrivers, drills, etc. Sharp objects, such as knives, box cutters, razors (both disposable razors and razor tools), scissors, ice picks, swords, etc.
No more than two spare (not installed in device/equipment) batteries may be carried.
There are only two types of lighter allowed on a plane. You can have a lighter containing liquefied gas, such as a BIC lighter with butane gas. Also allowed are lighters that use absorbed liquid fuel, for example, a Zippo lighter. Other types of lighters, like blue flame and torch lighters, are not allowed at all.
All e-cigarettes and vaporizers must be taken through the security checkpoint themselves and are not allowed in checked luggage. Checked bags get put through more intense scanning procedures that can damage or prompt confiscation of any vaping devices inside.
Banned from hand luggage: Drills.
With the exception of balls, many pieces of sporting equipment, such as baseball bats, golf clubs, ski poles, hockey sticks, lacrosse sticks, martial arts weapons, hiking poles, and tent spikes/poles, are prohibited from carry-on luggage and must be transported in checked baggage.
Is toothpaste considered a liquid? Yes, toothpaste is considered a paste or gel and therefore falls under the TSA 3-1-1 rule.
Yes, provided it falls within the size guidelines on the airline's website, you can use a backpack as a personal item or carry-on bag. Just remember that it needs to fit comfortably under the seat in front of you if it's a personal item and in the overhead compartment if it is a carry-on.
We recommend packing all liquids, gels, and aerosols that are over 3.4 oz or 100 ml in your checked baggage, even if they are in a secure, tamper-evident bag. Liquids more than 3.4 oz or 100 ml not in a secure, tamper-evident bag must be packed in checked baggage.
