Toolypet - Developer Tools Collection

Essential Tools for the Global Era

We shop internationally, invest in foreign stocks, and video conference with multinational teams. Two conversions have become daily necessities: currency exchange and time zone conversion.

"This item is $49.99 - how much is that with shipping in my currency?" "The meeting with the New York office is at 3 PM - what time is that locally?"

Handle these calculations quickly and accurately with Toolypet's Currency Converter and Time Zone Converter.

Currency Exchange Formulas Explained

Basic Conversion Formula

Converted Amount = Original Amount × Exchange Rate

Example: Convert $500 USD to EUR at rate 0.92

$500 × 0.92 = €460

Cross-Rate Calculation

When direct exchange rates aren't available:

Cross Rate = Rate(A/C) × Rate(C/B)

Example: Convert THB to BRL via USD

THB/USD rate: 0.029
USD/BRL rate: 4.97
THB/BRL cross rate: 0.029 × 4.97 = 0.144

Calculating True Cost with Fees

True Cost = Base Amount × (Exchange Rate + Spread) + Transaction Fees

Always factor in:

Bank spread (0.5-3%)
Wire transfer fees ($15-50)
Credit card foreign transaction fees (1-3%)

Time Zone Calculation Formulas

UTC Offset Calculation

Target Time = Source Time + (Target UTC Offset - Source UTC Offset)

Example: Convert 3 PM EST to JST

EST = UTC-5
JST = UTC+9
Difference = 9 - (-5) = 14 hours
3 PM + 14 hours = 5 AM (next day)

DST Adjustment

During DST transitions:

Spring forward: Add 1 hour
Fall back: Subtract 1 hour

Check official DST schedules for accuracy.

Frequently Asked Questions (FAQ)

Q1: How often are Toolypet's exchange rates updated?

Toolypet updates exchange rates daily using Federal Reserve (FRED) data. The exact update time is displayed on the Currency Converter page. For major transactions, verify rates with your bank before proceeding.

Q2: Can I convert between any two currencies directly?

Yes! Toolypet supports direct conversions between all 24 supported currencies. The tool automatically calculates cross-rates when needed, so you don't need to convert through USD first.

Q3: Does the Time Zone Converter account for Daylight Saving Time automatically?

Yes, the converter automatically reflects current DST status for regions that observe it. However, for future date conversions, be aware that DST transition dates vary by country and year.

Q4: Why is there a difference between the rate I see and what my bank offers?

Toolypet displays the mid-market rate (also called the interbank rate). Banks and exchange services add a margin (spread) to this rate. Typical spreads range from 0.5% to 5% depending on the provider and currency pair.

Q5: How can I find the best time for a meeting across multiple time zones?

Use Toolypet's Time Zone Converter to display up to 5 time zones simultaneously. Look for windows where all participants are within business hours (typically 9 AM - 6 PM). For US-Europe-Asia meetings, early morning US time often works best.
